Vampire Weekend performed at a Bernie Sanders rally in Manhattan's Washington Square Park tonight. Once again, they were joined by Dirty Projectors' Dave Longstreth. Accompanied by the Columbia University Metrotones, they performed "Cape Cod Kwassa Kwassa," "Unbelievers," "Rise Above," and "A-Punk." "I know we're down in NYU territory," said Ezra Koenig, acknowledging Columbia's choir joining them on the stage. "But if there's one place to put aside the bourgeois rivalries of private universities, it's at a Bernie Sanders rally. Also shoutout to CUNY." He also shouted out the CWA union members on strike in the crowd. Check out photos and footage below. Update 4/14 9:57 a.m.: Watch video of the full rally below. Vampire Weekend and Dirty Projectors begin their performance at the 15:50 mark.

The event also featured appearances from Spike Lee, Rosario Dawson, Shailene Woodley, Tim Robbins, Linda Sarsour, and Graham Nash. On Sunday, Grizzly Bear will perform at a similar event in Prospect Park, Brooklyn, joined by Danny DeVito, Justin Long, and Hawaii Congresswoman Tulsi Gabbard. The event is free and open to the public. On Monday, the night before New York's primary, TV on the Radio will play a Sanders rally in Queens. RSVP here.
