Every rapper considers their new record a classic, but R.A.P. Music might have a real claim. Killer Mike mixes the personal with the political in a genuinely artful way, examining racist America through case studies from Ronald Reagan’s policies to his own father’s police career, all delivered with mean-mugged Atlanta shape-throwing. Tracks like Butane (featuring El-P) and R.A.P. Music itself offer an opportunity to combine neck-snapping with purposeful, intelligent flow in a way not seen since Outkast’s heyday.
