It's easy to take Diesel Island for granted, to forget that it's still one of the strongest purveyors of classic country music in town. Once a regular at the long-gone Frederick's Music Lounge, the band — led by veteran singer Kip Loui and the Bottle Rockets' Brian Henneman, and featuring new members Tim McAvin and Spencer Marquart — Diesel Island now finds a home and gigs in a catch-as-catch-can fashion. And though its setlist is still anchored in '70s twang, the band doesn't need to stretch out. Nobody plays the great songs of '60s and '70s country music — from Waylon to Merle to Buck to all outlaw points in between — quite like these veterans.
