Ten Years After - Undead (1968) LP

Undead is a live album from Ten Years After, recorded in May 1968 at a small jazz club, Klooks Kleek in London, and released in August of that year. The performance combined blues, boogie and jazz, fused with more traditional rock and roll with a 1950s jump blues style. The album "clearly illustrates" Alvin Lee's "eclectic" use of the pentatonic scale mixed with other modalities.
