NERDS—For tonight's #NerdNightOut, Portland's charming geek sisters the Doubleclicks will play songs from their latest album, Dimetrodon, and share the stage with hilarious comedian Bri Pruett. If that's not enough, they'll also be accompanied by the folkpop of Sarah Donner. I mean, all of them won't perform at once, but it'll still be pretty good. EH
