In a move designed to raise the blood pressure of math teachers in the greater Chicago area, Chief Keef has announced that his stellar new mixtape, Bang 3, will be followed by another offering: Bang 3 (Part 2). To promote the latter half of the last third of a trilogy of mixtapes, the Windy City ex-pat today drops "Bouncin," a preposterously strong cut produced by DPBeats and Keef himself. Remember the coughing during the hook on "War"? At one point on "Bouncin," the Glo'd one raps, "Something, something, something, I forgot now/I was thinkin' 'bout the guap, then pulled my Glock out." There are hairpin turns in the beat, guns that went to college (like Kanye!), Andy Milonakis shoutouts and lamentations about your girl's wig. The cover art pays homage to Keef's accountant's least favorite sport, paintball. A few listens in, XXL was unable to pick up any shots at Rahm Emanuel. But we're still looking.
