Fred and Sherry,

I'll second Sherry's recommendation for drum tracks at http://www.mididrumfiles.com The author of the drum tracks and I became Internet friends when I was looking for some drum tracks when I was taking some jazz piano lessons (in which I failed miserably). Although his drum tracks are inexpensive ($35), I thought I'd save myself a few bucks and offered to trade a copy of MidiNotate for his drum tracks, and he took me up on the offer.

Cheers
