I was there too. Great show but the sound in the Circle (not the upper circle) wasn't great. I saw Ryan Adams from the upper circle in October and it was one of the best sounding gigs I'd ever seen, but Arcade Fire were hampered a bit by the sound. They didn't seem completely happy themselves as they kept pointing to turn it up or down. Still, although I haven't really listened to the new album that much, I remain to be convinced about it though last night I thought it sounded much stronger. Highlights for me were definitely the version of (Anti-Christ Television Blues) that ended the first encore - brilliant track, the segue between Power Out and Rebellion, the superb version of Haiti, and the sight of Regine drumming! Of the new stuff (apart from Anti-Christ), I thought Keep the Car Running and No Cars Go were particularly strong.
The crowd was amazing. A lot of people belted back every word of the new stuff. It really is no wonder that bands love coming to Dublin and to such a great intimate venue like the Olympia.
