Butch Walker and the Black Widows + Locksley

As a producer and songwriter, Butch Walker is as responsible as anyone for the high-gloss tween-rock template heard on records by Kelly Clarkson and Lindsay Lohan. Yet each of Walker’s solo albums is a treasure for power-pop nerds. He comes to town with a new one, I Liked It Better When You Had No Heart. Openers Locksley play dancey rock songs with a soulful edge.
