Black Diamond Heavies emerged in 2004 out of Nashville, forging a raw blues rock sound built on a two-piece setup: keyboards/organ driving the groove and drums pushing the rhythm. The project began with core members John Wesley Myers (Reverend James Leg) and Van Campbell, with Mark 'Porkchop' Holder joining through 2006 before the lineup shortened to a keyboard/drums duo. Known for a growling, Tom Waits–like vocal delivery and a chemistry that breathes energy into every performance, the Heavies carved a niche in the underground blues scene. Their work blends blues, punk blues, and soul, delivering smoky, high-energy shows that connect with fans who want real, unpolished live music.
