Before she formed the riot grrrl act Bikini Girl in 1990, singer Kathleen Hanna was just another private school student trying to find herself. Contrary to popular opinion, the teachers at trendy Evergreen College in Olympia, Wa. didn't take kindly to her literary experiments so she refrained from letting her emotions go. But then she met underground writer Kathy Acker and realized she didn't need to hold back. Acker helped her channel her more extreme impulses, and it wasn't long before Hanna was fronting the abrasive and openly feminist Bikini Kill. Hanna's history is well documented in the The Punk Singer, a terrific documentary that shows just how off putting the band's music (and politics) could be. The movie screens at 7 tonight at the Rock Hall. Tickets are $5.50, free for Rock Hall members and free with Rock Hall admission. (Niesel)
