What started with a cassette recorder, a microphone and a 100-mile commute from Brooklyn has blossomed into a 30-year musical love affair with Philadelphia and the region. MIlkBoy Studios, the brainchild of Tommy Joyner and Jamie Lokoff, will celebrate 30 years of recording and music with a block party on South Street in Philadelphia on Sept. 21 in front of MilkBoy venue.
