Keyboardist Ayad Al-Adhamy pounds out a dance-y jingle as the crowd grooves along.

During "Moth Wings" Angelakos jumped on his keyboard stool as young couples cuddled to the song's lyrics of love. "This is the first time we've played a lot of these [new songs] live," he later said.

While some fans braved the wind outside to snap photos of the Statue of Liberty, a mob slammed beers and danced through Passion Pit's set -- including a group of 20-something girls in high heels, who fell each time the boat swayed.

The event was also a party of sorts for Angelakos, whose 22nd birthday is today, May 19. What, no ice cream?

Angelakos, frosting smeared across his face, pounds out another tune.
