Here is some new audio from one of Pro Era's own top spitters, Kirk Knight, as the gifted emcee lays a mean 16 over this boom-bap-esque production. It bears a real gritty, real New York feel to it and it's borrowed from from the latest Underground Airplay mixtape that dropped on LiveMixtapes.com recently. The project also features some of rap's brightest talents like Black Dave, Joey Bada$$ and Big K.R.I.T. to name a few. Press play below to tune in.
