This live album features the finest moments from Chicago blues godhead Muddy Waters's three-night 1966 stand at San Francisco's hippie-rock mecca, the Fillmore. In an era when acolytes like the Rolling Stones were emerging as his torch-bearers, Muddy reasserts his primacy in a hard-hitting set full of signature tunes like "Got My Mojo Working" and "Hoochie Coochie Man," with no small amount of assistance from a rock-solid band that includes the guitars of Sammy Lawhorn and Luther "Georgia Boy" Johnson supporting Muddy's own devilish slide work.
