Girls Rock Charleston is back with its second summer showcase at the Music Farm. Over the course of four days this week, 70 girls and trans youth from the ages of 8-16 will pick up instruments, form bands, learn songs, and then perform them in front of hundreds at the downtown venue on Saturday night. The Girls Rock summer program also teaches its campers empowerment through classes on self-defense, self-image, zine-making, and more. At lunchtime they rock out too, as they become the audience for performances by local and national bands. Gracie Aghapour, one of Girls Rock Charleston’s founders (and one of our cover story profiles, see page 25), assures us that each camper will learn to play an instrument by the end of the week. The campers get to choose from keyboard, drums, bass guitar, and electric guitar. “There will be some campers who’ve never picked up an instrument before,” Aghapour says. “Some have been playing for a long time. They help each other out.” With the number of campers more than doubling since last year, the crowd at the Music Farm is expected to easily surpass 2011’s attendance of about 300. The admission fee goes back to the nonprofit organization to fund next year’s camp and provide need-based financial aid to campers.
