Alt-J is out with a new video for their first single, "Fitzpleasure". They've already released a trippy video for Tessellate. If this is your first time hearing Alt-J, remove the rock that's been placed over your home and check out their debut album, An Awsome Wave. Easily one of the best new releases of the year, and it's already garnered Mercury award nominations. They've just finished playing the Bowery Ballroom here in NYC. Check out a video of them playing "Tessellate" by opening it with "Interlude I" backed by a chorus after the jump. We're you there? Let us know what you thought of the show in the comments.
