FORMED JUST ABOUT a year ago from four very disparate corners of the Hip-Hop United States, Slaughterhouse brings the beastly lyrical pedigrees of its four component MCs (Jersey’s Joe Budden, Long Beach, Calif.’s Crooked I, Brooklynite Joell Ortiz and Detroit-bred Royce Da 5’9 ) to bear in aggressively straightforward rap music. Furthermore, it seeks to do nothing less than hotwire and run away with the rapidly flagging and disintegrating hiphop music industry, to poise itself as the harbinger of a new and prosperous golden age. Elevated goals to be sure, but in Slaughterhouse’s case, the “show and prove” seems to be a constant and breathless pursuit—all of the group’s initial output is swollen with lyrical blood and the members describe recording their forthcoming self-titled debut (out this week) in a tireless few days.
