Killer Mike and El-P: Fuckboys know the combination ain’t healthy, and the rest of us can only wonder at how unlikely and miraculous the whole thing is. Mike went from OutKast understudy to strip-club poet laureate to resident underground-Atlanta firebrand, whereas El saw the demise of his grassroots Def Jux jitter-rap empire just before he became a wizened uncle to New York’s resurgent indie-rap scene. And now the two are Violent Rap Friends, flexing their unexpected but genuine chemistry all over this clanking, buzzing, thunderous, enormously satisfying rappity-rap clinic. Now that I think about it, maybe the combination is healthy, at least to the non-fuckboy population. –Tom [LISTEN]
