This Eagle Rock quartet's missionary garb is a symbol of its dedication to "rock out," not preach gospel. So no, they're not part of the LDS church but they're just as pesky. Since 1998, until its recent closure, they were the unofficial house band at Mr. T's Bowl. They're also notorious for taking their show to the streets like punk-rock guerrillas, crashing Coachella and the storefront of Amoeba with two battery-powered amps, a megaphone and a sound influenced by Devo, Dead Kennedys and The Voidoids. On Saturday, they celebrate 16 years of being a DIY punk band that's wacky enough to write an anthem for fleeing authorities. Badtown Boys, The Black Widows and Bloody Brains join L.A.'s geek-punk misfits for a Sweet Sixteen celebration that should get weird.
