Funkladelic (and Parliament, George Clinton under his own name, etc.) are all great! Have you checked out Funkadelic's "I'll Bet You"?
WFMU hell yeah...I probably listen to them more than any other radio station, even though you can't usually dance to it.
Their programs aren't all like this. On weekends they go into some marvelous, and deep, specialty programming and stuff. They even have a show which plays only stuff recorded before 1925 or so.
