Sharla June & the Mayhaws play an eclectic mix of blues, folk, bluegrass and rock and roll that makes Bessie Smith sound like Iggy Pop, and the Ramones sound like Hank Williams. They innovate, but with a respect for tradition, walking a line between the sunny sounds of old-time folk and bluegrass and the gritty darkness of old blues and hardcore gospel and country songs. It’s the sound that wafts out of green-lit dashboards in big old 50s cars as they rocket through the soft, black summer night. It’s an after-hours jam session in the kitchen of that juke joint off the highway, the one your mama told you to stay out of. But of course you don’t stay out. How could you? Not when smoky-voiced Sharla June & the Mayhaws are in town.
