I might suggest going to www.dustygroove.com and start browsing around. Probably one of the premier sources for such stuff on the web. Even if they do get a little too enthusiastic in their descriptions at times... Good people to deal with & lightning-fast turnaround on orders.
Like Herbie Hancock's funk, more please
I've found myself listening to Herbie Hancock's finkier albums (Thrust, Manchild, Headhunter) over and over again lately. Who else was (or is) doing that kind of funky fusion?
