In five steps this text tries to convey a semiotic analysis of the phenomenon of ‘live VR music concerts’.Through this paper it becomes clear that the meaning of live music and virtual live music is not always clear. Virtual does not want to be like the real. It does not intend to create the same music experience. It is a globalising trend that seeks to go beyond. In contrast, maybe the real becomes more like the virtual. Experimenting with virtual experiences results eventually in the dissolving of the boundaries between the real and the virtual. The meaning of live music is changing and is strongly interpreted in the context of culture. Pandemic culture insinuated the interpretation that VR is just arriving, but actually it was already here for a while. With the semiotic square we analysed the virtual and real through the ‘here and now’. It is the ‘here and now’ (authenticity?) that gets questioned in live virtual concerts. It is legit to present a live concert in other ways, because that is one of the aims of VR. The virtual concert does not necessarily want to substitute real-life concerts. Peircian interpretations led into new kinds of music experience and new music industries/business models. A virtual concert experience constructs experience of identities of experience of collectivity that are real. Even in a manipulated or determined world the emotions that music creates are real. ‘Liveness’ shows the (intersubjective) power of music.

The early history of the so-called ‘neighbouring rights’, as part of the history of copyright, has so far been given very little attention by scholars. This article sheds light on a European contest over the rights in sound recordings during the 1930s, 1940s and 1950s. This forms an important part of the background to the Rome Convention of 1961. The article first looks separately at how musicians’ unions and the record industry were raising different demands for protective legislation, motivated by the use of new electronic media. At the beginning, no one imagined that these protections would be bundled together as ‘neighbouring rights’. While the International Labour Organization (ILO) put great efforts into creating a convention protecting only the performers, another actor turned out to be more influential in the long run, proposing a hierarchical bundling of rights in which only record companies were entitled to compensation for the use of recordings. This actor was the Fascist government of Italy. The article argues that there are some continuities from the legal philosophy of Italian Fascism to the system of ‘neighbouring rights’ established in the Rome Convention.

Ghislaine Boddington - This paper is going to discuss, what will be called, 'The Internet of Bodies'. Our physical and virtual worlds are blending and shifting our understanding of three key areas: (1) our identities are diversifying, as they become hyper-enhanced and multi-sensory; (2) our collaborations are co-created, immersive and connected; (3) our innovations are diverse and inclusive. It is proposed that our bodies have finally become the interface.

The COVID-19 emergency has had a profound impact on the artistic and cultural sectors, and on performing arts in particular. The lockdown required the suspension of all live performances and rehearsals, including the cancellation of seasons and festivals. Because physical proximity is an essential component of live shows, this sector will be on pause longer than the others. Since the early stages of the lockdown, Italian theatre has developed several online initiatives to counterbalance the suspension of its activities. These efforts have aimed at maintaining contact with the remote theatre audiences, by extending the presence of artists, theatres and performances in the online context. However, they have also provided an opportunity to reflect at large on the digital transformations of performing arts. The following contribution reflects on how we are researching the online response of the theatrical sector from the perspective of sociology and media studies. The paper aims to contextualise the phenomenon within the processes of theatre mediatisation and digital transformation of liveness, and to present what we think are the most urgent research questions in this direction. The first part of the article introduces the theoretical premises of the investigation. We present the frame of theatre mediatisation by analysing three interrelated processes: the mediatisation of dramaturgy through the concept of transmedia; the mediatisation of theatrical presence, with the debate on digital liveness, and the mediatisation of the theatrical relationship through social media. The second part will analyse some of the main online initiatives of the theatre sector, observing how they fit into the previously introduced mediatisation processes. The third part will observe how users have responded to the initiatives presented on social media by some of the main Italian theatres. In the conclusions, we will discuss which research questions we consider crucial to connect the analysis of this critical moment to the main themes of sociological and media studies research on performing arts.

In recent years, the expansion and use of mobile Internet and social media have changed live music engagement and fandom quite considerably. It has not only allowed fans to find and connect with each other at shows, but also to tweet and text concert set-lists and other information as they happen, thereby allowing non-attendees around the world to feel part of the event. This study examines the responses of fans engaged in this activity, identifying the key themes and patterns apparent within this behaviour, arguing that fans are using social media and mobile technology in an effort to contest and reshape the boundaries of live music concerts. It demonstrates how these online tools are involving fans that are not physically present at the show, seemingly incorporating them into the real-time “live” experience. This article explores how fans of prolific touring artists U2 and Tori Amos undertake this, with assigned concert attendees tweeting the set-list to online fans, where they gather to enjoy the show together, from the comfort of their computers.

Through recent artistic practices and technology of interactive systems for music, composition and improvisation have more and more blended and interconnected with each other – a sui generis situation now called comprovisation. The concept of comprovisation applies equally well to the spontaneous generation and manipulation of computer graphics, especially as such graphics are systematically coordinated audio-visually, while being subject to spontaneous manipulation by a performer.
This is explained in terms of the Fluxations and FluxNoisations Human Body Interfaces, interactive dance systems that generate music and graphics spontaneously in response to hand and body movement. They enable spontaneous expressive shaping of coherent complexity and variety. Thus a multi-layered multimodal experience arises. The aesthetic experience of this multimedia spectacle relates to experiences of various prior music and visual art of the 19th, 20th, and 21st centuries, as well as to hypothetical physical realities. Thus a kind of cybernetic phenomenology of art is pursued and enacted through an embodied cybersynthesis of art with simulated alternate reality. Call it a pragmatic speculative realism, an adventurous technoetic ‘what if.’ As compared to more traditional forms of improvisation, the opportunities for risk-taking and aesthetic exploration rise to a new level of uncertainty, as the reactions of the improviser simultaneously draw from and target both visual and aural modalities, such that the intentions toward each fuse together."

Nesta investigação tentamos contribuir para um enquadramento teórico da ciberformance, a performance que acontece em plataformas, ambientes e mundos virtuais e que se caracteriza por ser ao vivo, mediada, intermedial, multimodal, híbrida, liminar, colaborativa e interventiva estética e socialmente, sendo low cost e usando tecnologia livre e acessível.
Há duas décadas que acções performáticas se desenvolvem através da Internet, ligando utilizadores e públicos distribuídos geograficamente. Fóruns e ambientes textuais de jogo foram os primeiros espaços usados por ciberformers tendo estes, mais tarde, apropriado ambientes gráficos e mundos virtuais online.
Na primeira parte deste estudo investigamos o lugar da ciberformance e os aspectos do habitar o virtual que se afiguram importantes para entender o processo criativo deste género artístico. O carácter aberto livre e comunitário de plataformas e mundos virtuais cria lugares que estão para lá da simulação, proporcionando uma ampliação do virtualmente humano que favorece a prática da ciberformance. Esta implica uma actividade que se desenvolve através de interfaces visíveis e que possibilita a compreensão desses espaços não como imersivos mas sim como ampliações hipermediadas.
Uma passagem pela relação histórica entre a performance e a tecnologia permite-nos sediar a genealogia da ciberformance nos movimentos vanguardistas do século XX.
Com base na nossa própria prática artística nos contextos referidos e em recente produção académica sobre a performance digital criámos um enquadramento que visa possibilitar uma melhor definição e compreensão deste emergente género artístico. A análise da forma, conteúdo e processo criativo de algumas performances específicas, conduziu-nos a uma tipologia operativa que apenas existe na intersecção dos seus tipos. Estes são definidos pelo seu desenvolvimento através da palavra, através da construção de código e através do corpo em interface com a tecnologia.
Procuramos aqui abrir caminho para a análise do contributo deste género para o panorama mais vasto da relação entre a comunicação à distância, a interacção humano computador e a arte contemporânea.

In this paper, we use two audio/visual performance projects based on differing design approaches to consider the relationship between designer and user. Using the examples of OverWatch and Waves, we examine similarities between classical designer-user development processes and practice-based scenarios where designers draw upon native knowledge of the design space.

This article proposes a theory of mediated presence, defined as the sense of presence-despite physical absence-made possible by technology. Pushing the boundaries of media, the theory integrates various notions of presence at a distance: telepresence in telecommunications and computer-mediated communication, liveness in broadcasting and on the Internet, and the epistolary presence of antiquity. Theoretically, it adopts a social construc-tivist approach to long-term communication history, with an emphasis on technological breakdowns. The core discussion addresses three criteria for a historical, comparative analysis of mediated presence: dissemination versus dialogue, transmission-reception time lags, and levels of disembodiment. Refuting axiological and technology-centered views of history, the article concludes that increased technological options for presence at a distance have remained essentially ambivalent for users who vacillate between the need for distance and the search for connection. This article proposes a theory of mediated presence, defined as a sense of the presence of one or more persons, despite their physical absence, through technological mediation. Covering human history since the advent of correspondence, the theory subsumes different notions of presence at a distance, originating in several research traditions: computer-mediated communications, telecommunications, and liveness in broadcasting and on the Internet, as well as the epistolary. Suggesting new dialogues between compartmented fields, it broadens the definition of media in long-term history through systematic comparisons and qualifies our contemporary sense of a radical change, born of recent technology affordances. I begin with a multidisciplinary review of theories of presence at a distance, then explain the use of the expression-mediated presence, which both broadens and specifies the notion of presence at a distance across technologies and historical contexts.

Martin Parker’s gruntCount is a multi-version, configurable composition for improvising musician (or musicians) and computer. Performers embark on a journey through sound processing modules that are specifically customised to individual playing styles. It exists in no fixed state, yet allows for a growing set of rehearsable, replicable and configurable pieces, in which all musical material, timing, overall duration and levels of effort are managed by the live musician. In order to optimise elements of flow and of liveness in each performance, gruntCount challenges traditional definitions of 'piece', ‘system’ and ‘instrument’, instead establishing an environment for human-machine improvisation that serves the musical result and not the system itself. This paper refers to a selection of sound examples from the bass clarinet version (2012-14) and examines formal time-shaping possibilities within a structured performance, while exploring the environment’s qualities of coaction and configurability in an era of new score types.

The problem of documenting performance is discussed via viewer testimonies of Jerzy Grotowski’s practices. On the one hand, Erika Fischer-Lichte’s notion of performance involves the viewer’s experience in the aesthetic work. On the other hand, this conception situates documenting the experience beyon­d the realm of performance. In light of the limitations Grotowski placed on documenting and disseminating his own work, it is especially interesting to analyze viewer testimonies. The author examines several texts by professional viewers, analyzing the ways they reconstruct the performances they saw and the elements on which their reconstructions are based (literary texts, personal texts, and texts by other views). A key element in these descriptions is the appeal their authors make to an experience that cannot be expressed. The appeal to this experience shapes a specific temporality, combining the time of viewing and the time of writing, and activating not only the possibility of analysis but also the experience of the various senses.

What is so eventful about an event movie's arrival to the multiplex, and how does this eventfulness function as both an industry strategy and audience experience? Synthesizing an analysis of trade discourses, promotional campaigns, and manually-curated box office data, this article considers how the concept of eventfulness emerged as a discursive construction and spatiotemporal formation used by the industry to promote moviegoing as more meaningful than other forms of media experience in today's "anywhere-anytime" and "on-demand" culture. Eventfulness situates the movie theater at the center of a specific, layered structure of time-a stretched sense of promotional anticipation and cultural nostalgia which climaxes during an ephemeral moment-and space-a discursive space of cultural buzz leading up to the event, a local experience community marked by fan participation, and an imagined global audience which takes shape through the synchronization of the event as it simulates "live" broadcasting and connects audiences in time.

A dearth of research exists that examines live stand-up comedy from the audiences' perspective. This empirical article redresses this neglect by examining the appeal of live stand-up comedy to audiences and revealing their motivations for going to see live stand-up comedy. These interests are explored through an online survey and a series of semi-structured interviews with live stand-up comedy goers. The online survey uncovers the frequency of attending live stand-up comedy, the types of venues that stand-up comedy is seen in, the types of venues that audiences prefer to experience live stand-up comedy in, and the extent to which individuals attend live stand-up comedy alone or accompanied by others, and if so, who they attend with. The one-to-one semi-structured interviews extend the investigation by analysing the specific reasons why audiences attend live stand-up comedy. Five main themes emerge from the semi-structured interview data: respecting the stand-up comedian; expecti...

The article explores the affective consequences of the new mode of instant access to enormous levels of musical recordings in digital format. It is suggested that this " musical superabundance" might weaken the individual's ability to be affected by music in everyday life, while at the same time leading to a renewed interest in collective experience, in ways which are not limited to established notions of musical " liveness ". According to a theory of affect influenced by Spinoza, what is at stake is the capacity of the body to be affected by music. The article proposes that a renegotiated relationship between collective and individual modes of experiencing music can be conceptualized with help of Spinoza's distinction between two kinds of affections: actions and passions. After scrutinizing the interface of hardware like Apple's Ipod and online services like Spotify, the article proceeds by discussing three musical practices which can all be understood as responses to the superabundance of musical recordings: (1) the ascetic practice of " No Music Day " ; (2) the revival of cassette culture; (3) the " bass materialism " associated with the music known as dubstep. While none of these approaches provide any solution to the problem of abundance, they can still be understood as attempts to cultivate a " postdigital sensibility ". The article tries to conceptualize the postdigital in a way that transcends the narrower notion of "post-digital aesthetics " that has recently been gaining popularity. Finally, it is argued that such a sensibility has a political significance in its potential to subvert the contemporary processes of commodification.

The last two decades in India have seen an enormous growth of satellite television. News has established itself in the meanwhile not merely as a source of information but also of entertainment. Available in all regional languages through several competing channels, and presented elaborately, television news has come to establish a mode of address, which defines one’s sense of time and space, and configures one’s sense of the dramatic situated in others’ stories. This article engages with the implications of “liveness”—as material and as affect—toward convergence of news narratives. Discussing two of the most widely covered recent stories—Aarushi Talwar’s murder and Baby Falak—the article foregrounds the class antagonism and scandalous anxieties of Indian televisual publics, and argues that news television invites us to trade liveness for news. Thus, news media not only liberates itself of the rigor of news production but also entertains us by reaffirming our deepest anxieties and competing with other modes of intertextual entertainment available on rival channels.

Come cambia l'idea del "live", con le piattaforme, e dopo il distanziamento sociale imposto dalla pandemia?
La parola live sembra diventata un ossimoro: concerti annullati o rimandati, mentre sui social media abbondano performance musicali presentate come "dal vivo".
Il concerto live è un modello narrativo e produttivo, replicato dai media fuori dallo spazio della compresenza fisica e del qui ed ora, la cui trasformazione ad opera delle piattaforme digitali è un processo in atto da tempo.
L'articolo, a partire da alcuni esempi come la performance di Travis Scott su Fortnite, ragiona su come sta cambiando l'idea di performance nello spettacolo e nei media digitali

The proliferation of two screen or connected viewing on multiple devices (smartphones/iphones, laptops, tablets/ipads) simultaneously are reshaping the ways that TV broadcasters programme, schedule, and deliver programmes and content. This article examines how the notions of liveness and live TV are being reshaped within this context. Focusing on the BBC and Channel 4 the article explores how and why these two British PSBs are reinventing and promoting liveness and in particular live media events across platforms and devices. With the BBC’s ‘BBC Live’ content delivery system as case study, the article argues that rather than seeing liveness as a thing of the past, BBC regards live TV as core to its multi-platform strategy. Today, the BBC uses two of television’s traditional traits – liveness and reach – to crowd out and gain a competitive edge on streamed content and VoD providers like YouTube, Netflix and AmazonPrime across platforms and devices.

In some musical genres, professional performers play live shows many times a week. Arduous touring schedules bring encounters with wildly diverse audiences across many different performance ecologies. We investigate the kinds of creativity involved in such repeated live performance, kinds of creativity that are quite unlike songwriting and recording, and examine the central factors that influence musicians’ wellbeing over the course of a tour. The perspective of the professional musician has been underrepresented in research on relations between music and wellbeing, with little attention given to the experience of touring. In this case study, we investigate influences on positive and negative performance experiences for the four professional musicians of Australian pop/rock band Cloud Control. Geeves conducted intensive cognitive ethnographic fieldwork with Cloud Control members over a two-week national Australian tour for their second album, Dream Cave (2013). Adapting a Grounded T...

This paper investigates representations of performance and the role of the archive. Notions of record and archive are critically investigated, raising questions about applying traditional archival definitions to the performing arts. Defining the nature of performances is at the root of all difficulties regarding their representation. Performances are live events, so for many people the idea of recording them for posterity is inappropriate. The challenge of creating and curating representations of an ephemeral art form are explored and performance-specific concepts of record and archive are posited. An open model of archives, encouraging multiple representations and allowing for creative reuse and reinterpretation to keep the spirit of the performance alive, is envisaged as the future of the performing arts archive.

Modern face recognition systems are vulnerable to spoofing attack. Spoofing attack occurs when a person tries to cheat the system by presenting fake biometric data gaining unlawful access. A lot of researchers have originated novel techniques to fascinate these types of face tampering attack. It seems that no comparative studies of different face recognition algorithms on same protocols and fake data have been incorporated. The motivation behind this paper is to present the effect of face tampering on various categories of face recognition algorithms. For this purpose four categories of facial recognition algorithms have been selected to present the obtained results in the form of facial identification accuracy at various tampering and experimental protocols but obtained results are very fluctuating in nature. Finally, we come to the conclusion that it is totally unpredictable to select particular type of algorithm for tampered face recognition.

The COVID-19 emergency had a profound impact on the artistic and cultural sectors, and on performing arts in particular. The lockdown required the suspension of all live performances and rehearsals, including the cancellation of seasons and festivals. Because physical proximity is an essential component of the live shows, this sector will be on pause longer than the others. Since the early stages of the lockdown, the Italian theatre field developed several online initiatives to counterbalance the suspension of its activities. These efforts aimed at keeping the relationship with the remote theatre audiences, by extending the presence of artists, theatres and performances in the online context. However, they also provided an opportunity to reflect at large on the digital transformations of performing arts. The following contribution reflects on how we are researching the online response of the theatrical sector from the perspective of sociology and media studies. The paper aims to contextualise the phenomenon within the processes of theatre mediatisation and digital transformation of liveness, and to the present what we think are the most urgent research questions in this direction. The first part of the article introduces the theoretical premises of the investigation. We present the frame of theatre mediatisation by analysing three interrelated processes: the mediatisation of dramaturgy through the concept of transmedia; the mediatisation of theatrical presence, with the debate on digital liveness, and the mediatisation of the theatrical relationship through social media. The second part will analyse some of the main online initiatives of the theatrical sector, observing how they fit into the previously introduced mediatisation processes. The third part will observe how users have responded to the initiatives presented on social media by some of the main Italian theatres. In the conclusions, we will discuss which research questions we consider crucial to connect the analysis of this critical moment to the main themes of sociological and media studies research on performing arts. 1 L'articolo è il risultato del lavoro congiunto degli autori.

This paper provides a formal specification and proof of correctness of a basic Generalized Snapshot Isolation certification-based data replication protocol for database middleware architectures. It has been modeled using a state transition system, as well as the main system components, allowing a perfect match with the usual deployment in a middleware system. The proof encompasses both safety and liveness properties, as it is commonly done for a distributed algorithm. Furthermore, a crash failure model has been assumed for the correctness proof, although recovery analysis is not the aim of this paper. This allows an easy extension toward a crash-recovery model support in future works. The liveness proof focuses in the uniform commit: if a site has committed a transaction, the rest of sites will either commit it or it would have crashed.

Input devices like touch-sensitive dance mats, plastic guitars or the Wii-Controller (or nowadays Microsofts Kinect as well) add a special quality to “playing” music in a double sense: Music games like for instance Guitar Hero, Rock Band and the Dance Dance Revolution back from 1998, or the slightly different Wii Music, visualize the musical movements and ask the player to perform himself, thus shifting the aspect of “playing” to the position in front of the screen. With this music, which is usually listened to in a domestic context or in a public place such as a pub, is combined with processes that can be seen, heard and felt on and in front of the screen and a completely new situation is created.
By presenting some examples this article examines the relation and interaction of musical, visual and physical movement while playing those video games by focusing on the English term “performance” in its double sense: On the one hand in the sense of an activity, on the other in the sense of a single performance which is exclusively constituted by its execution on as well as in front of the screen as dynamic, artistic activity. The article is based on a talk given in 2009.
