It has been YEARS since I have seen a show there. This will date me, but the last two shows I saw there were Jane's Addiction with Happy Mondays, or was it Elvis Costello with The Replacements. Anyway......I was never impressed with the acoustics and the set-up for concerts. Despite its history and fame, it is an older arena...so the far seat are TRULLY far from the stage. You are prolly better off with one of the outdoor venues anyway. I love outdoor shows.
I say we all go to Denver for the Red Rocks show! We can all wave white flags (with a Fairtrade theme instead of a Sunday Bloody Sunday tilt).
