http://multitrackmaster.com/Stems, mostly; lots of rips from Rock Band, but a few other things too.
There are some raw tracks of things which perhaps some of you might be aware of floating around out there...
I have the multitracks of Spoonman and it's pretty cool, too. I don't know where they came from. A whopping five tracks for the drums. Kick, toms, overheads. (I think there's a close snare mic in there. I think.) Guitars are a stereo pair, and there's an acoustic layered in there that's very apparent with the guitars soloed. Someone must have made them from something, as they aren't raw tracks, but it doesn't seem like a Rock Band rip to me either. Probably some intern somewhere. But I digress.
