Supergroup Slaughterhouse consists of Crooked I, Royce da 5'9", Joe Budden and Joell Ortiz, who combined forces in 2009 to rip the hip-hop game to shreds. All street buzz and promo, the group's first single, "The One," from its self-titled album, was dropped on Budden's Twitter account, and the masses responded immediately — and favorably — to the impeccable rhyming schemes and lyrical firepower that were packed into one rap group. Shortly afterward, the MCs signed with Shady/Interscope, and they've been slanging rhymes and bravado to much acclaim ever since.
