Aragon easily the worst Ive been to, followed by Millenium Park, then Soldier field. It's a shame all that money and work put into the venues, and they still cant get a decent sound. Millenium Park sounded like I was listening to a AM radio right above my head, needless to say I was disapointed. Aragon, well....its the aragon, I feel sorry for any engineer who isnt a master of delay, mixing there. And the most disapointing was Soldier Field, depending on where you sit it sounds like a single auratone trying to fill a concert hall.
