This their second release and it's a live album recorded at the small but influential jazz club, Klooks Kleek, in London, May 1968, and released in August of that year. It features a rip-snorting version of I'm Goin' Home which was later put onto the b-side of Hear Me Calling. Alvin Lee's playing is very much more jazz-influenced than on later records, especially on thr epic workout of Woodchoppers Ball. Awesome stuff.
