I already looked it up, I've just never heard of it or heard of anyone playing there before. Kind of a weird choice if you ask me, but then again Arcade Fire has never been one to shy away from that.
Yeah, I can't really give my two cents, since I don't live in California, but looking at its Wikipedia page it seems like it holds a lot of awards shows.
Seems like decent capacity, combined with theatre aesthetics, so doesn't sound bad at all to me. My show's in an arena/coliseum, but I still am stoked.
