Undead is a live album by Ten Years After, recorded live at the small jazz club, Klooks Kleek, in London on May 14th 1968, The show combined Blues, Boogie and Jazz playing that merged more traditional Rock and Roll with 50s-style Jump Blues. Alvin Lee, Leo Lyons, Chick Churchill and Ric Lee together became one of the biggest club attractions in England. Their music knows no compromise - it's straight down the line. It's loud and tough - but honest. Undead captures the excitement and raw energy of the band's live performances.

When originally released in 1968, the album was only 38 minutes long, due to the timing constraints of vinyl. As the band's tunes were all pretty long, there were only five tracks on the original issue. The expanded edition of Undead contains 4 additional tracks of the performance and is available on vinyl for the very first time. The remastered audio is pressed on 180 gram audiophile vinyl and Side D is beautifully etched.
