Sleep's debut album "Volume One" was released in 1991. Frequently compared to bands like Saint Vitus, Sleep soon gained a devoted fanbase within the developing doom metal scene.
The band's next album was sent to Earache Records, as a demo. Recorded at Razors Edge studios in San Francisco, with Billy Anderson handling production, the tape showcased Sleep's love of all things retro, from the blatant Black Sabbath/Blue Cheer influences, to their fixation with 1970's-style tube amplification. The label immediately signed the band and released the tape exactly as it was received.
Sleep's "Holy Mountain" (1992) is widely considered a seminal album in the evolution of stoner metal. The album's release was followed by a potentially lucrative offer from London Records, and Sleep signed with them.
Under their new contract, Sleep began work on their third album, "Dopesmoker," in 1995. Much to the dismay of executives at London records, "Dopesmoker" was a single song more than one hour long. London Records declared the album unmarketable and refused to release it. Sleep returned to the studio and then submitted their second attempt at the new album. They had retitled it "Jerusalem," re-written some of the lyrics and trimmed it down to a "lean" 52 minutes, but it was essentially the same as Dopesmoker. London Records again refused to release it. Frustrated and generally unhappy with the situation, the members of Sleep decided to disband.
