This past Saturday night, the dynamic duo of Chris Bailoni and Clay Frankel (better known as Grapetooth) headlined a sold out show at Lincoln Hall. The unofficial Pitchfork aftershow came on the heels of the pair's announcement that they'd been signed to Polyvinyl Records, who will release Grapetooth's debut record some time this fall. If you missed out on the rambunctious show--which ended with fans climbing onstage during debut single "Trouble"--check out our photos of the show below.
