A few of the members here on Guitartricks tried to start a collaboration like this a while back. (the brainchild of Educatedfilm)

It fizzled out after a few weeks of nothingness. Skee1 and I did a spin-off from the collab, a two minute blues track, but that was about all that happened.

Maybe you'll be the one to get us motivated again . . .
