Gritty Pittsburgh boom-bapper Boaz is back with "Mathematics," the first taste of Vol. 2 of his Real Name, No Gimmicks mixtape series (head here to stream the very solid first installment).

The Rostrum Records signee is prepping his debut album for later this year, and on this cut he gets lyrical about counting money and spitting bars over a dusky '90s beat, scratches and all. Stream "Mathematics" below, and be on the lookout for the full mixtape to drop later today.
