Bio From AllMusic.Com
When Crooked I, Joell Ortiz, and Royce Da 5'9" joined Joe Budden on his 2008 mixtape Halfway House, the chemistry on their collaborative track meant "Slaughterhouse" the song would quickly become Slaughterhouse the hip-hop supergroup. Seeing as how Budden, Crooked I, and Ortiz all had issues with their former labels -- Def Jam, Death Row, and Aftermath respectively -- other tracks recorded at their initial meeting bypassed the usual music distribution channels and were leaked to the net, including "Move On" which gave the music press the group's backstory in song. They recorded their debut album in a mere six days, signed to the E1 label, and released their self-titled, debut in 2009. Due to sample clearance issues, the final product did not include the promised single "Woodstock," but in keeping with the group's alternative marketing plan, it was released via Budden's Twitter account. - David Jeffries
