Singer-songwriter Kina Grannis may have won a contract with Interscope and an appearance in a 2008 Superbowl commercial through a Doritos contest, but she's an easy fit for the indie cred-booster that is Daytrotter. Visiting the hallowed Horseshack in downtown Rock Island, Ill., Grannis strummed through four acoustic cuts from the Stairwells LP, including "The One You Say Goodnight To," the single she debuted as a video over on MTV recently.
