A supergroups go, it doesn't get much more super than the hip-hop duo Prhyme, featuring legendary producer DJ Premier (Gang Starr) and Eminem protégé Royce Da 5'9" (Bad Meets Evil, Slaughterhouse). Premiere's beats are as succinct and propulsive as they were back when he was crafting them for the likes of Notorious B.I.G. and Nas, while Royce's lyrical backflips are matched by verses from A-list guests like Common and Schoolboy Q. Prhyme's slap-happy boom-bap and old-school record-scratching will send '90s acolytes reeling, with tracks like "Dat Sound Good" and "Underground Kings" sounding distinctly old school.
