2007’s finest bluegrass-rock ensemble comes to Sac

Forget Death Cab for Cutie’s bland indie garbage. Head to Freeborn Hall on April 22 for the outstanding opening act: the Cave Singers from Seattle. Mixing washboard bluegrass with raw rock ’n’ roll, the Cave Singers will have the crowd on its feet, stomping in time to the music one minute and feeling and their heartstrings tugged like strings of a banjo the next. 8 p.m. Tu 4/22. $30.50. Freeborn Hall at UC Davis, 1 Shields Avenue; (530) 752-1910; http://freebornhall.ucdavis.edu.
