First things first, it was an absolutely awesome show. The Wexner Center is a full sized theater, but the show was a Black Box show, where they curtain off the stage and build a small riser on one end of the stage while the audience packs on to the rest of it. It dramatically decreases the performance space and creates a really intimate atmosphere, which I think was perfect for a band like this. I'd say there was probably about 200 people there at most.
The opening band was...well...fronted by a guy who was 100% nuts. I don't really have anything else to say about them. After intermission, Vampire Weekend came out, and they looked exactly like you'd expect an indie rock band from New York to look. They sang, they danced, it was rad. One thing that stuck out, though, was the drummer. He had to have been on something, because aside from being insanely awesome at his instrument, he just looked out of it during downtimes.
All in all, awesome fucking show. My only gripe is the fact that they don't tour with any sort of strings player, which I think makes each song lack just a little something from the album that gives the songs a certain kind of character, or catchiness. (Also, no harpsichord on M79. Sad.)
