The debut full-length CD from Nashville’s Black Diamond Heavies proves once again that size isn’t everything. Two guys on drums and keyboard – yep, no guitar – churn out some of the most bone-shaking, fuzzed-out, blues rock to see the light of day. While the duo cites influences as varied as T-Model Ford, Lou Reed, Tom Waits and Muddy Waters, you can hear spiritual guides R.L. Burnside and the Black Keys in the mix as well. John Wesley Myers (electric organ, “knife and vocal”) and Van Campbell (drums and vocals) reach into the murky bottom of the swamp rock genre and stir it up into a virulent brew of sonic excess. From Myers‘ gravelly, snarling vocals to the potent, reverb-drenched rhythms, there is nothing light about this record. The unrelenting hold of the Heavies sneaks up on you, with opening track “Fever in my Blood” morphing a simple drum beat into a demonic, trance-inducing barrage of crashing symbols, pulsating keyboard and growling vocals. Other tracks like “Leave it in the Road,” “Poor Brown Sugar,” and “Might be Right” threaten to grind you right into the woodwork of the shadowy, Southern back-woods bar you imagine hearing these guys play in, while the crowd of sweaty bodies around you gyrates, possessed by some unknown force. “Let Me Coco” is a cool-down moment, an almost breezy, jazzy respite from the heat, and you’ll need it before going along for the dangerous ride of “White Bitch” and “Guess You Gone and ….” Don’t forget to breathe.
