Sleep is a stoner doom metal band from San Jose, California. Active during the 1990s, Sleep earned critical and record label attention early in their career. Critic Eduardo Rivadavia describes them as "perhaps the ultimate stoner rock band" and notes they exerted a strong influence on heavy metal in the 1990s. However, conflict with their record company had contributed to Sleep's breakup by the end of the decade. The band reformed, performing sporadic live dates, in 2009.
Early years 
Sleep evolved in the early 1990s from the band Asbestosdeath, which was established by vocalist/bassist Al Cisneros, drummer Chris Hakius, and guitarist Tom Choi. Asbestosdeath expanded to a quartet with the introduction of Matt Pike on guitar, and recorded two singles - "Dejection" for Profane Existence and the self released "Unclean". Choi departed, and would later found Operator Generator, It Is I, Noothgrush, and Las Vegas' Black Jetts. Asbestosdeath recruited Justin Marler as replacement and the band adopted the new name, Sleep.
Recording era 
Their 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. Marler quit the band soon after to take up life as a monk, leaving the band as a power trio for the recording of their Volume Two EP, which was released officially by Off The Disk Records in 1991.
The band's next album was sent to the independent label, Earache, as a demo. Recorded at Razors Edge studios in San Francisco, with Billy Anderson, Chris Savino 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. Around this time, Earache released its first Black Sabbath Tribute album, and Sleep contributed a cover of "Snowblind".
Under their new contract, they 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.
After Sleep 
In 1998, Sleep and their former manager granted approval to Tony Presedo, head of Tee Pee Records and friend of the band, for the release of Jerusalem posthumously as an "official bootleg". One year later, Jerusalem was given an official legitimate release by The Music Cartel in the US and Rise Above Records in Europe.
Finally, in 2003 the original version of Dopesmoker was officially released by Tee Pee Records. It is generally considered the definitive version of the album. An excerpted version can be heard on Jim Jarmusch's Broken Flowers original soundtrack.
In 2007 a CD compilation of both 7" releases of the pre-Sleep band, Asbestosdeath, was released on Southern Lord Records.
In May 2009, Sleep reformed to perform two exclusive reunion sets in England as part of the All Tomorrow's Parties music festival. In the shows the band performed for the first time a song that had previously been intended for inclusion on, and wrote during the Dopesmoker recording sessions and widely unheard entitled 'Antarcticans Thawed'.
On November 19, 2009 Al Cisneros confirmed in an interview with The Obelisk that Sleep will be reuniting in the fall of 2010 for some US dates. It has also been confirmed that Jason Roeder (of experimental metal band Neurosis) will replace Chris Hakius on drums.
The group played the ATP New York 2010 music festival in Monticello, New York where they performed Holy Mountain in its entirety. They followed up this performance with a tour of the rest of the United States, playing headlining dates and festivals, through September.
On April 14, 2012, Sleep headlined the 17th annual Roadburn Festival. A band statement for which reads “Sleep are honored to attend the Symposium of Iommic Research, Tilburg at Roadburn”.
On May 5, 2012, Sleep played at Betong in Oslo, Norway. Supported by A Storm of Light, and Conan.
On June 2nd, 2012, Sleep played a headlining set in the Scion Rock Fest in Tampa, FL. This was a free festival put on by the alternative (albeit Toyota-funded) music and art label, Scion AV. Other acts included Down, Psychic TV, Sick of It All, Merzbow, and more. Matt Pike's birthday was celebrated on stage at the conclusion of the set, with cake.
