Remember the Brian Eno & David Byrne album "My Life in the Bush of Ghosts" released in 1981? It's been remastered and re-released this spring.
They offer the original 24 tracks of 2 of the songs for everybody to download, to remix and to use in any non-commercial songs. You can also upload your remixes onto their web pages for everybody to listen to (although the web site is very buggy and I haven't been able to upload anything there).
My first version is the "Don't Fix What Ain't Broken Remix" on Help Me Somebody: http://studio-mobile-rollo.net/Bush-of-Ghosts/HelpMeSomebody-NoFixRemix.mp3
You can also find it here: http://studio-mobile-rollo.net/index_files/Page487.htm
Here's some info from their pages:
"This is the first time complete and total access to original tracks with remix and sampling possibilities have been officially offered on line. In keeping with the spirit of the original album, Brian and David are offering for download all the multitracks on two of the songs. Through signing up to the user license, and in line with Creative Commons licenses, you are free to edit, remix, sample and mutilate these tracks however you like. Add them to your own song or create a new one. Visitors are welcome to post their mixes or songs that incorporate these audio files on the site for others to hear and rate.
