Cypress Hill are an American hip hop group from South Gate, California, and were originally called DVX, but changed their name following the departure of Mellow Man Ace in 1988. Their self titled debut album, produced by DJ Muggs (who went on to produce House of Pain's first album, and work on other Soul Assassins projects like Funkdoobiest) was released in August 1991, and included the singles "Phuncky Feel One" (the B-side of which was "How I Could Just Kill A Man"), "Hand On The Pump" and "Latin Lingo" (which combined English and Spanish lyrics). The success of these singles led to “Cypress Hill” selling 2 million copies in the US alone. Second album ”Black Sunday” debuted at number 1 on the Billboard 200 in July 1993, and with their debut still in the charts, Cypress Hill became the first rap group to have 2 albums in the Top 10 of the Billboard 200 at the same time. Fuelled by the hit "Insane in the Brain", the album went triple platinum in the US, selling over 3.25 million copies, and Rolling Stone magazine named the band “Best Rap Group” in their 1994 music awards (as voted by critics and readers).

Third album, 1995’s “Cypress Hill III: Temples of Boom” sold 1.5 million copies on its way to number 3 on the Billboard 200, buoyed by hit single "Throw Your Set in the Air". In 1996, Cypress Hill appeared on the first “Smokin' Grooves” tour, featuring Ziggy Marley, The Fugees, Busta Rhymes and A Tribe Called Quest, and also released a 9 track EP, “Unreleased and Revamped”, containing rare mixes of past material. However, in 1997, the band members focused on their solo careers. Muggs released “Muggs Presents ... the Soul Assassins”, featuring contributions from Wu-Tang Clan, Dr. Dre, KRS-One, Wyclef Jean and Mobb Deep. B-Real appeared with Busta Rhymes, Coolio, LL Cool J and Method Man on "Hit Em High" from the multi-platinum “Space Jam Soundtrack”, contributed to The Psycho Realm’s self titled album, and also appeared with RBX, Nas and KRS-One on the single "East Coast Killer, West Coast Killer" (from Dr. Dre's “Dr. Dre Presents the Aftermath” album). Sen Dog formed Los Angeles based rap rock band SX-10, and released the “Get Wood” sampler (as part of SX-10) on the label Flip.

Back together again in 1998, Cypress Hill released “IV”, which went gold in the US, and featured the hit singles "Tequila Sunrise" and "Dr. Greenthumb". 3 other songs from the album, "16 Men Till There's No Men Left", "Checkmate" and "Lightning Strikes" all featured in the video game “Kingpin: Life of Crime” in 1999 (with B-Real also contributing some of the voices of the people in the game), the same year that the band released a greatest hits album in Spanish, “Los Grandes Exitos En Espanol”.

2000’s “Skull & Bones”, a 2 disc release, explored 2 different genres (with "Skull" composed of rap tracks and "Bones" composed of rock tracks), and reached the Top 5 on the Billboard 200, and number 3 in Canada. The band also released “Live at the Fillmore”, recorded at the famous San Francisco venue, during the same year, and then continued their rock experimentation on the “Stoned Raiders” album in 2001 (which failed to make the US Top 50). The year closed with the band appearing in the film “How High”.

The band released “Till Death Do Us Part” in March 2004, with lead single "What's Your Number" featuring Rancid’s Tim Armstrong on guitar and backup vocals. The album also features appearances by Damian Marley, Prodigy and Twin of Mobb Deep. In December 2005 a best of compilation album entitled “Greatest Hits From the Bong” was released, and, having fulfilled their contractual obligations with Sony Music, Cypress Hill’s next album will be released on Suburban Noize Records.

Cypress Hill are the first Latino group to have platinum and multi-platinum albums, and have sold more than 18 million albums worldwide (including over 11 million records in the US).
