Perfect Pussy’s songs were barely discernible amid the nonstop noise and crashing as the band quickly blasted through its set on the Blue Stage, but that hardly seemed to matter. This punk band is all about bashing your head in, sonically speaking, and it accomplished that. Lead singer Meredith Graves, wearing a striped dress, rarely stopped moving as she screeched and twirled, occasionally lifting her skirt for peeks at her undergarments, while her bandmates attacked their instruments as if they wanted to break them. Not surprisingly, a few people in the audience were inspired to crowd-surf. (Robert Loerzel)
