Greyboy is a DJ and producer. The Greyboy Allstars are a live band
incorporating some of the musicians that play on Greyboy's sample-based
stuff like the album "Freestylin'" to which you were refering in your
posting. If you want to hear the band rather than sampled loops with the
musicians playing over them, you should pick up the Allstars' album "West
Coast Boogaloo", out on Greyboy's own label. Anyway, I'm sure there will
be a posting soon after this one from someone involved with Greyboy or
The Allstars explaining this in detail.
