Many thanks to all who commented on Twitter and Facebook on yesterday’s photo – especially Alistair Leadbetter and Rangel Luis Manuel.

FRANCE – FEBRUARY 23: Michel Foucault, Roland Barthes and Pierre Boulez in Paris, France on February 23, 1978. (Photo by Gilbert UZAN/Gamma-Rapho via Getty Images)

From left to right, the people are Elliott Carter, Pierre Boulez, Roland Barthes, Jean-Claude Risset, Gerald Bennett, Michel Decoust, Michel Foucault, Gilles Deleuze.

[Update: on Facebook, Caleb Salgado suggests it isn’t Elliott Carter, but might be Milton Babbitt. Babbitt seems less likely, but it might not be Carter. There are some other images of this person with Foucault here. There is also an image of Carter in 1978 here (picture 4)]

There are some details on the event here.

Rangel also sent a link to a video of the event, organised by IRCAM at the Centre Pompidou. It includes Foucault’s contribution, which I’d not seen before.

It can be seen here [Update February 2023: this link seems to be broken; but it is also here].
