Query: The future of acid jazz

Greyboy brings something that a lot of the "smooth" jazz artists don't: groove! No rap, no vocalists, just excellent beats & HAROLD TODD and KARL DENSON. If you enjoyed this like I did, check out GREYBOY ALLSTARS, GALACTIC, CORDUROY, SLIDE FIVE (Rhode Trip), and of course, GREYBOY (Freestylin'). This is definitely the future of acid jazz.
