OpenSound also looks interesting.
Opsound is a record label using an open source, copyleft model, an experiment in practical gift economics, a laboratory for new ways of releasing music.
In its first phase of operation, Opsound is gathering material for an open sound pool which will be drawn on for the creation of a series of online and real-world microlabels.
It’s a nice idea (CC interview with founder Sal Randolph). But unfortunately the open pool of audio can’t actually host any of the audio files, so there’s already some geocities “file not found” links. Is a persistent media archive of open source and open submission material possible? (MP3.com has started charging. Submisson to IUMA doesn’t seem to be working.) Can this kind of archive only be maintained through the fickle p2p labyrinth or out-of-pocket bandwidth expense?
