Zoo TV 1992 ... I honestly do not remember. Public Enemy, maybe? That show is a blur.
PopMart 1997 ... um. They had a dude playing On Wisconsin as a flugelhorn solo. They were really shitty, and I am blanking on their name.
Vertigo ... Kings of Leon ( I didn't hate them like others did), Damien Marley (fun, but only because I was finally in the ellipse), Keane (loved them), Kanye West (was happy to get to see him)
360 ... Snow Patrol (yay, I like them), Black Eyed Peas (LOL), Lenny Kravitz (liked him a lot more than I thought I would), Interpol (I only saw about 20 minutes of their set, however), Reeve Carney's band (exactly), and Arcade Fire (one of the reasons I schlepped to Moncton)
I would not be surprised if they had someone big and bland like Imagine Dragons or Bastille.
Hozier is great in concert, I can attest. Lykke Li was ... kind of awkward, but I love her music. My absolute top wish list would be Elbow, but it's not going to happen in the US.
