Trish Klein started Po' Girl as a side project when the Be Good Tanyas took time off so Frazey Ford could deliver her first baby. Klein enlisted multi-instrumentalist/singer Allison Russell for a sound that mixed folk, blues, trad jazz, and Americana, or maybe Canadiana, since the band hails from Vancouver. Their tunes were marked by inventive arrangements and the blissful harmonies of Klein and Russell. The band became a foursome with the addition of Diona Davies and Awna Teixeira, two more talented multi-instrumentalists and singers. Their recent album, Home to You, is full of plainspoken poetry and deep feeling, and songs dealing with the varied notions of home. In person, their sweet harmonies and low-key virtuosity spin a cozy, comforting web of song. Po' Girl plays Sunday, Dec. 7 at the Freight & Salvage (1111 Addison St., Berkeley). 8 p.m., $18.50, $19.50. TheFreight.org

A bit lower-profile than some of the East Bay's other lively arts, choreography is as vital as any of them and nearly as long-lived -- after all, Isadora Duncan found truth in movement at Berkeley's Temple of Wings, and Merce Cunningham leapt into his career from the Mills College stage. Since 1979, local choreographers have showcased upcoming dances at Works in the Works, a performance series hosted by Choreographers' Performance Alliance, and the longest-running series of its kind in the Bay Area. The 30th edition takes the stage on November 14, 15, 21, and 22, at Eighth Street Studio (2547 Eighth St. #16, Berkeley), with local artists and performers like Jessie Feller, Jennifer Mellor, SF State University Dance Theater, Aileen Kim, and the Shawl-Anderson Youth Ensemble sharing the bill with select talents from around the state. Each night brings a unique lineup of original pieces and works in progress, followed by a moderated discussion with one of the choreographers. 7:30 p.m., $10. WorksintheWorks.org
