American hip-hop group formed in South Gate, California in 1988. Lineup: B-Real (Louis Freese, vocals), Sen Dog (Senen Reyes, vocals), DJ Muggs (Lawrence Muggerud, production), and Eric "Bobo" Correa (percussion, since 1995). Pioneers of West Coast hip-hop and the first Latino rap group to achieve major US commercial success.
Nine studio albums starting with Cypress Hill (1991). Commercial peak: the debut and Black Sunday (1993, featuring "Insane in the Brain"). The 1995 album Cypress Hill III: Temples of Boom shifted toward darker, slower production. The group has been outspokenly pro-cannabis throughout its career, contributing to the cultural mainstreaming of marijuana legalization.
