Looking for tracks of just drums...

[kettles]

I want to compile a couple CD's to listen to when regular music gets boring. I'm looking for tracks just of mostly grooves (solos are alright too). I know about the Led Zep outtakes, and a sizable collection of Maiden, Judas, Megadeth, and Sabbath album tracks.

Anyone know of any other stuff around on the net? Doesn't have to be from songs or albums, just recordings of drums, preferably groove/beat oriented.

Edit - Here's an Iron Maiden one to give you an idea what I'm talking about: http://www.youtube.com/watch?v=r0cw9uXxfmI
