Now there is a festival "corruptive climate" for experimental music. Well that is really very experimental and arty stuff - sometimes hardly to be called music, but sometimes it sounds also nice - generally that goes into direction of electronic music.
Wednesday 12/12/12 there is a lecture and discussion about sonic architecture at 6 pm. and at 8 pm. there will be a concert (or maybe rather kind of soundinstallation) of birch tree sounds.
The place is: Ausland, Lychener Str. 60, 7,- EUR admission
They wrote in the flyer that they will start on time - last time when I was there they were 1,5 hours late.
