I would go if I was in town. Ratatat is amazing. Last time I saw them play a few months ago, they were in front of a crowd of about 2000 people. It is a real treat to see them in a small venue, if you can. Once they played at Walters which has capacity of 150.
i think you can appreciate it a lot more live and in the right atmosphere. maybe thats dumb to say but ive had some pretty cool nights seeing stuff like that live. jammin it in my apartment or car sometimes not so much.
