This Los Angeles indie quintet started 2006 as a MySpace-only ensemble, but by 2008, the Los Angeles Times and Rolling Stone had declared them a band to watch. Indeed, The Airborne Toxic Event's songs--a sometimes strange, but always provocative mix of violin melody, intense lyrics, and guitar riffs--are known to inspire massive sing-alongs, a few tears, and incredible energy. 8 p.m. The Bluebird Theater [2], 3317 E. Colfax Ave., 303-377-1666, $14, tickets [3]
