1) Sleep is a stoner doom metal band from San Jose, California, United States. 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.
