Oakland's own Loop Station! comprises the classically trained duo of Sam Bass and Robin Coomer, and their unique mix of cello and raw, lyrical emotion has earned them a gaggle of Bay Area fans. They perform live, each with a foot-pedal-controlled loop station tool that they use to layer cello and voice tracks over one another. They'll be playing two sets this weekend at Outside Lands, one early on Friday and one on Saturday. Here's a video of them performing "The Last Time I Saw You" at DNA back in '06.
