This past weekend, a huge thunderstorm hit Chicago’s North Coast Music Festival, fucking up a bunch of Passion Pit’s gear and forcing the band to turn a few Canadian shows into DJ sets instead. But they got everything working or replaced in time to play their “Constant Conversations” on the Late Show With David Letterman last night. And they also became the latest participants in the Live On Letterman webcast series, playing a full hour-long set at Letterman’s Ed Sullivan Theater. Watch the video of that whole set below.

We’ll post footage of the actual on-air performance as soon as it shows up online.
