Girls Rock! Rochester, the rad local non-profit organization that empowers young girls through music, is having its annual cover show benefit. Think Halloween meets karaoke night, except it's actually rehearsed and there are some pretty decent local musicians playing it. About 15 bands, covering the likes of Rilo Kiley, Neil Young, and the Rolling Stones this year, will each play 15 minute sets. It's a fundraiser and all the proceeds go to benefit the Girls Rock! Rochester summer camp. Rock.
