I make my own loops sampled from records. Here's how you do that.
How about Garibaldi's "Code of Funk"? 8 songs from the Oakland Zone album in full length and with complete transcriptions.
Stanton Moore's Groove Alchemy also has many grooves in it but it's mostly just one or two bars of the basic idea and the play alongs are original songs.
Frank, are you looking for drumless stuff?
