One of the earliest LPs to earn the psychedelic label—almost certainly the first to include the word itself in the title—the Elevators' 1966 debut can be seen as a concept album about drug use as a path to higher consciousness. Although electric-jug player Tommy Hall pushes that message in his lyrics, what sets this collection apart is the punk-like intensity of Roky Erickson's howling lead vocals and the hard-edged garage stomp of experiments like "You're Gonna Miss Me" and "Fire Engine."
