The Differentials- Drive On LP. The Differentials peeled out of an Austin, TX garage and revved up the big block delivering a distinctive dose guitar heavy rawk ‘n roll. On their debut album they power shifts through nearly a dozen tracks of riff heavy guitar rock! A quality 10 song platter for fans of the Lazy Cowgirls, Cosmic Psychos, Jeff Dahl and the Humpers. The sound of The Differentials is spreading faster than fumes at a drag strip! Come get a whiff!
