Sotto Voce, the second edition of the one-day festival for improvised silence and noise, is at the State51 Factory just off Brick Lane next Saturday. Amongst other things, Aki Onda, of Cassette Memories fame and Matthew Bower, of Skullflower fame, are both on, as well as Benedict Drew, whose soundtracks for Emily Richardson's films are super. Come down. A bunch of tracks to listen to and pre-booking available at the Sotto Voce website.
