Philadelphia-based rapper PnB Rock is on the come up in 2017, pouring gasoline on a path that's already on fire. He emerged on the scene in 2014 with a single that featured on MTV Jams, "My City Needs Something," which is in response to the alarming rise of violent crime in Philadelphia. He's only been in the game for a short time, but has already dropped four mixtapes and released his first studio album, "GTTM," in the beginning of 2017.

PnB Rock opens for Jadakiss and Fabolous on Friday, April 14, at Main Street Armory, 900 East Main Street. 8 p.m. $55-$75. mainstreetarmory.com; pnbrockmusic.com.
