They really were pretty damn great. Better than I was expecting. I have to agree with the comments on the live drummer, that makes it so much better. The venue was a bit too large for them I thought.
For me the highlights were Lazuli (particularly the part about halfway through where it breaks down then Victoria starts singing "like no other you can't be replaced"), New Year, Zebra, Wishes, Myth and Irene, which was great as a closer. That guitar is absolutely sublime. Norway and Silver Soul, my two fav Beach House tunes, both fell a little flat.
Victoria's pretty attractive as it turns out, when she doesn't have her hair all over her face. Her voice is amazing. I was pretty astounded, I don't think she missed a note all night, it was just like the records except better. The guitarist dude is terrific as well.
Over the first few songs I was kind of wishing I was at Hot Chip and if I had my time over again I'd go see them instead, but after a few songs I'd forgotten about it and was just enjoying Beach House. I'll just have to try and stop thinking about what I missed and appreciate what I saw. I'm not nearly as big a fan as the rest of you but it was a great show.
