The world has (or had) the Van Halens, the Allmans and the Stinsons. Little Rock has the Kerbys. Those other famous rocker brothers have married TV stars and Cher, played at the Fillmore and trashed hotel rooms. The Kerbys, Josh and Kevin, played Vino's without their shirts one time. They also have rocker neck beards and menacing tattoos, respectively. With Kevin, known for his prowess as a singer/songwriter, kicking out chunky riffs on the ole electric guitar, Josh vamps and hollers out the lead vocals. They sound cowpunk-ish, but rawer and more well-rounded. Bryce, a refugee from the Contingencies, plays drums and the bassist is known almost exclusively as Slaughter House or sometimes just Slaughter. San Antokyo is celebrating the release of its debut album; the cover charge gets you a copy. Magic Hassle, an American Princes side project featuring David Slade, Matt Quin and Burt Taggart, opens the show along with barroom heroes Smoke Up Johnny, who after playing out prolifically and touring, briefly, with the Green Day alter ego, Foxboro Hot Tubs, probably won't be playing again for a long, long time. So make it count.
