St. Vincent is one of the most ferocious and compelling live acts operating right now, and that means she’s an ideal choice for the Late Show With David Letterman’s Live On Letterman webcast series, in which bands play full sets in Letterman’s Ed Sullivan Theater. Last night, she played on that stage for nearly an hour, entering through the crowd with a bizarre ballerina walk and then ripping through much of her recent self-titled album. And judging by the robotic art-star persona she projected all over that stage, Annie Clark is approaching Björk levels of weirdo swagger, with the added benefit that she can absolutely shred on her guitar when she so chooses. Watch the performance below.

St. Vincent is out now on Loma Vista.
