Governors Ball attendees got a special treat Friday when Vampire Weekend frontman Ezra Koenig showed up on stage during Chromeo's set at the New York fest.

"There's this guitar riff I like to play sometimes," said Chromeo's Dave Macklovitch (aka Dave 1), as he began playing Vampire Weekend's "Cape Cod Kwassa Kwassa." Koenig then interrupted him jokingly: "Dave, I showed you the riff," he said. "It's really not that hard."

The trio proceeded with "Kwassa Kwassa" before launching into Chromeo's own "Bonafied Lovin."
