Best Music Collaboration Sites

Hi. Could anyone recommend a good bunch of music collaboration sites? I’ve got a track that I’ve got some ‘guide’ lead bits for and I’m wondering if I could find a half-decent guitarist to either record them for me, or provide me with something way better that I could use. (All for non-profit of course.)



Thanks I’ll add that to my list. I’m just trying out at the moment. Its taking forever to upload my tracks though. Be interesting to see how this site works.

Anyone out there interested in my stuff, look me up - SparkyNZ on the site.
