/* 
Schemawound track from the SIGNALVOID compilation.
SIGNALVOID is a noise compilation. Participants were asked to create up to three tracks, each of exactly one minute in length, with no gaps of silence at the beginning or end. Download the free compilation here: http://archive.org/details/SignalvoidMp3 or http://archive.org/details/SignalvoidFlac
Physical copies are available here http://signalvoid.bandcamp.com/merch/signalvoid-2
