Slaughterhouse is a Hip Hop supergroup consisting of rappers Crooked I, Joe Budden, Joell Ortiz and Royce Da 5'9". The group formed in late 2008 after Crooked I, Joell Ortiz and Royce Da 5'9" appeared on the song "Slaughterhouse" from Joe Budden's album Halfway House. They took their name from the song. The group is planning to release a full-length album August 11, 2009 on the label E1 Music (formerly Koch Records).[1]. During July, '09 each member will release an EP of original material. First will be Royce with The Revival followed by Budden with The Escape Route, Crooked with Pig Face Weapon Waist, and then Ortiz. No word yet on the title of Ortiz's EP.[2] All this will coincide with a summer tour to promote both the group and the album including a spot on the annual "Rock the Bells" tour.[3] The group is notable for the lyrical abilities of all four members and their large internet following.[4]

The members of Slaughterhouse all share some degree of controversy from their past in the music industry. Crooked I (Long Beach, CA) was signed to Suge Knight's Death Row label from 1999-2003, but left after his projects were shelved amidst the disintegration of the label due to Knight's continuing problems with the law. Joe Budden (Jersey City, NJ) had initial success when he signed to Def Jam in the early 2000s, but for reasons unknown, fell out of favor with Jay-Z when the latter became head of the label. Budden eventually left Def Jam and released a diss track to Jay-Z entitled "Talk to 'em."[5] Joell Ortiz (New York, NY) was signed to Dr. Dre's Aftermath label but left after he was informed that his album would not be released until both Eminem and Dr. Dre released their respective projects. Finally, Royce Da 5'9" (Detroit, MI) is known for his falling out and feud with former friends Eminem and D12, though the two sides have since reconciled.

All four men address these issues in the Slaughterhouse song "Move On (Slaughter House Remix)," informing any interviewers out there that their pasts are behind them and that questions pertaining to these events are not relevant.[6] A video for the song was released in March 2009.
