GIRL POWER ROCK FEST The Charlotte chapter of the National Organization for Women (NOW) is celebrating its 40th anniversary, and the Girl Power Rock Fest - in its third year - is part of the festivities. The rock comes after documentaries and NOW info sessions. Yet, for all the revolutionary potential of this setup, there's precious little riot to the grrls on this bill (you probably won't hear anything along the lines of Bikini Kill's "Don't Need You"). In fact, with so many dudes in these bands - though not in singing roles - these shows ostensibly seem to be more about gender equality than girl power. Straightforward local rockers Grown Up Avenger Stuff and Shot Silk play Chop Shop's main stage. Danielle Engle of bluesy swoon-rockers The Between and jazz-folkie Devon Elizabeth play outside, while there's mid-'00s-reminiscent indie pop and lounge funk courtesy of The Local Traumatic and Chasing Pedestrians, respectively, at Evening Muse. Free. 8 p.m. Evening Muse. Chop Shop.
