It has been three years that we were waiting for this. Following a post from 2010 (seehere), someone has finally uploaded Chris Marker's philosophical series of 12 TV essays from 1989. Here is one, about music naturally, that is totally fascinating. Sorry for the French. There are no subtitles. Featuring Iannis Xennakis, Michel Serres, Cornelius Castoriadis et alii.
