Butch Walker, formerly of SouthGang and Marvelous 3 and now enjoying a successful solo career, visits the Tralf tonight to perform.  After standing out as the guitarist in metal-leaning SouthGang, Walker spent the rest of career handling the vocals, streamlining his sound for a more mainstream pop audience, and producing for acts such as Weezer and Dashboard Confessional.  He and his band, the Black Widows, will hit the stage at 8 p.m., and admission is $20.
