Earlier this week, Grizzly Bear played Chicago's Metro, and during their set, they had Victoria Legrand of Beach House (who does harmony on "Two Weeks) hop up to perform "Slow Life," their track from the upcoming New Moon soundtrack. The video above proves that the song is indeed pretty slow, but doesn't give us the entire thing. Now that we got a taste, let's all go back to complaining that this song exists for the soundtrack to a movie about vampires who pull out and werewolves who don't wear shirts. [You Ain't No Picasso]
