 What the Livestream Does to Live Music 
The first consequence of the digital transition in the music industry is to bring about a crisis in the physical media market which has not yet finished delivering all its implications. At the same time, live music has regained a central position as an axis of value creation, for artists as for other players in the ecosystem. And this specificity was partly due to the difficult dematerialization of the ‘hic et nunc’ of the concert. With livestream, whose development has accelerated sharply with the Covid19 pandemic, live music is created and broadcast online, via ad hoc technical solutions, but above all via social content sharing platforms. Put into perspective by an analysis of the practices observed during the year 2020, the positioning of the Twitch livestream platform leads to an interest in the methods of content creation, the interactions that take place around it, as well as the economic models that emerge.
