Broken Bells, with The Morning Benders. Showbox at the Market, 1426 First Ave., 628-3151. 8 p.m. Sold out. One would think that the collaboration between Brian Burton (Danger Mouse), the producer who brought us Gnarls Barkley, and James Mercer, the songwriter who brought us the Shins, would have been an innovative and genre-breaking affair. Instead, Broken Bells released a record of lo-fi, slightly lifeless pop songs that cruised up the Billboard charts on the backs of bankable names, not musical ingenuity. Their live show is said to bring about as much (or little) action as the record, a notion that doesn’t seem to be fazing anyone – enough of you were willing to spend $35 a pop for this show to sell out.
