Dum Dum Girls' massively catchy debut album I Will Be ranked as our 13th favorite album of 2010, so we were delighted when these cool-as-ice ladies agreed to stop by the office and play us a cover. We were doubly delighted that they chose "September Gurls" by Big Star, because then we can say dumb stuff like "Girls play 'Gurls'." Okay, maybe not. In any case, please enjoy this performance, and go visit this fun interview we did with Dee Dee about her favorite girl-group tracks.
