Cypress Hill is an American hip hop group from South Gate, California. Cypress Hill was the first latino group to have platinum and multi-platinum albums and one of the first rap groups to gain a following with fans of alternative and hard rock music. The band was originally called DVX, but the name was changed after Mellow Man Ace left in 1988. Their first album, which was self-titled, was released in August 1991. Its single was "Phuncky Feel One," but it was the B-side "How I Could Just Kill A Man" (formerly "Trigga Happy Nigga") that attracted more airplay on urban radio and college radio.

There is more than one artist with this name:

Biohazard was one of the first bands to regularly incorporate elements of both hip-hop and hardcore metal into their sound; since their lyrical fare dealt with the harshness of urban life and the resulting anger and frustration, which both genres of music have been known to address, the connection only made sense, especially in light of Anthrax's highly effective collaboration with Public Enemy on 1991's "Bring the Noise.

Hed PE, also known as (hed) planet earth and stylized as (həd) p.e., is an American rock band from Huntington Beach, California. Formed in 1994, the band performs a style of music which they refer to as "G-punk". Their music is primarily based in a fusion of punk rock and hip hop, but they have also been known to incorporate elements of heavy metal, reggae and other genres. After releasing three albums on Jive Records, Hed PE left the label to record independently, eventually signing with Suburban Noize Records in 2006.
