These online collaborations have been tried a lot over at Guitarwar, with some great results, I might add. (of course, they always have to shred a lot to prove that they're the greatest guitarist of all time) I tried one a long time ago, but it didn't work out because the other guy lost his internet connection for a while.
I can offer my "radical" rhythm skills, drum tracks, and maybe keyboard. I've got some web space too.
I suppose I should ask Eddy what style he wants to do?
Key: I vote for Ab Lydian. (or maybe not . . . )
