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, Royce Da 5'9", and Nino Bless appeared on the song "Slaughterhouse" from Joe Budden's album Halfway House. They decided to form a group, minus Nino Bless, and named the group after the song. The members of Slaughterhouse all share some degree of controversy from their past in the music industry. All four men address these issues in the Slaughterhouse song "Move On", informing any interviewers out there that their pasts are behind them and that questions pertaining to these events are not relevant. A video for the song was released in March 2009.
