In the isolating times of COVID-19, digital live streaming has been a key means through which artists connect with their audiences/community and audience members access live art and music. With performances mediated through digital live stream, artists and audience members alike are experimenting with strategies for connection, and indeed, for survival. This reconfiguration of sociality, of the liveness of community, threatens to endure beyond the pandemic. The Instagram Live music festival ‘Isol-AID’, which we examine as a case study in this chapter, prompts a discussion around arts accessibility as a measure of public health and wellbeing. Building on literature about social prescribing, we suggest that Instagram Live engages therapeutic forms of arts practice, and as such, could be offered as a new digital health resource. Using a critical posthumanist perspective, we think-through Instagram Live and streamed performance as posthuman assemblages to highlight the importance of non-human actants (such as phones, wifi, colours, sounds) in the production of the feeling of community, which is a social determinant of health. These creative methods of expression and connection encourage discussion around the importance of the arts in community health and wellbeing, a conversation that could not be more relevant than in the socially isolated world that is, this global pandemic.
