Only a fucking idiot who didn't know anything about song writing would say Sleater-Kinney sucks. Listen to "One Beat" and shut the fuck up. Sleater-Kinney is the greatest all female band of all time, and possibly some of the best song writing i've ever heard.
Just LISTEN TO 'ONE BEAT'.
P.S. I'm going to be there... at both... as soon as tickets go onsale.
