Paris Musique Festival: concerts in unusual places of French heritage. Boris Vian's former apartment, now inhabited by a relative of his widow, usually only received a smattering of visitors.

Another sacred place: the Son/Ré workshop where Pierre Henry composed some of his works. It will house several electro sets, with only around twenty spectators able to enter this seraglio. Sanseverino will perform there on Sunday. “I’m waiting to go in first to see if I like it,” he jokes.
