The long-awaited new mixtape from fast-moving Philly hip-hop trio Ground Up dropped today at Datpiff.com. Supernatural features collaborations from West Philly rapper Chill Moody, pop singer Patty Crash, and long-standing South Philly MC Reef the Lost Cauze – who’s been something of a mentor to the Ground Up guys over the years. You can listen to it in the player below, or download yourself a copy here. The release party for the record is set for The TLA on Saturday, September 29; get tickets and more information here.
