It's one of Little Rock's best holiday traditions. Local bands that are defunct or rarely perform reassemble on stage. Folks from out of town come. Folks who got married or had a kid and quit hitting the bars every weekend return. Everyone sings along. In scarves and Christmas sweaters. Or something like that. In any case, an opportunity to see Ashtray Babyhead, long Little Rock's go-to pop-rock act, play its hook-a-minute hits is one you shouldn't pass up. The band's members aren't often in the same city together —much less the same practice space. Ashtray Babyhead's guitarist, Jeff Matika, spends most of his time these days touring the world with Green Day. And lead vocalist Scott Cook is busy making inroads in the national pop scene with Julian Lennon and big money Internet entrepreneurs. With Jason Tedford (Iron Tongue and Year of the Tiger) on bass and Ryan Scott on drums. Ultimate Fakebook, The Dead Girls and Memphis' The Dirty Streets open.
