Following the departure of former lead singer and guitarist Mark “Porkchop” Holder, the Black Diamond Heavies have toured as a blues duo. Though it seems like a guitar would be the defining instrument in this type of band, drummer Van Campbell and pianist/vocalist John Wesley Myers manage to carry on just as well (if not better) as a two-piece. Myers has stepped up to sing lead vocals, and his growl is reminiscent of Tom Waits’. As Myers’ passionate voice hits deep lows and his hands vibrate across the piano, Campbell picks up the pace with booming blues beats. Hailing from Tennessee, the band uses its lyrics to address classic Southern topics such as religion, evil, drinkin’ — and the evils of drinkin’. Raise a glass to the Heavies, whose show brings both starlight and moonshine.
