You started a drummer thread and you've never heard of Bill Bruford? For shame!!!!!! Just kidding.....
He was Yes's original drummer, then was in King Crimson for years, did the brilliant first UK album (with Wetton, Holdsworth and Jobson) and had his own band for a time (Earthworks)....
He is in my top 5 of drummers, the guy is a technical wiz, incredible chops and great timing....the sound quality isn't great on this song but you can still hear how incredible Bruford is....
