This summer, Girls Rock Philly is giving 80 local aspiring female musicians ages 9–17 the opportunity to step from singing in front of their bedroom mirrors to the stage of World Cafe Live. The non-profit summer camp brought together girls from the greater Philadelphia area to learn to sing and play guitar, bass, and drums, building self-esteem along the way. The campers formed 15 bands, who are writing and rehearsing their own songs over the course of the week-long program. They also will have the chance to record a compilation CD in WXPN’s studios.

During the week of camp (going on now), GRP is live-blogging on its Tumblr, posting music, videos, and photos of the music-making in action. Check it out here. You can also keep up with the organization on Facebook and Twitter.

On August 13th, the Girls Rock Philly Showcase Performance will take place at World Cafe Live (Downstairs). Doors will open at 11:30 a.m. and the concert will begin at noon. Admission is $10 for the general public; tickets may be purchased online here or at the door. For more information, click here or call (215) 789-4879.
