Adept subway-taker Noah Brennan-Sawyer reported back from last night’s free Vampire Weekend show the Union Square Barnes & Noble with the following tidbits:

Tween girl to tween friend: “I started listening to Vampire Weekend after I read Twilight and got big into vampires.”

In a Q+A session, frontman Ezra Koenig said that VW’s songs are based on a class he took at Columbia called “Codes of Imperialism.” Die-hard fans will be disappointed to find that this course is no longer on the bulletin.

Another Ezra quote: “We always bring our academic studies into our artistic work.” Plus: “You can’t go back in time; you can’t go back to college…thank God.”
