And they were immense. Absolutely top form, better than I've ever seen them on any of the DVDs. There were about 8 people between me and the barrier, so we managed to get up pretty close! James was on top form, Petrucci rocked, I loved Jordan's tilting keyboard as well! Myung seemed to be having a great time (I think I saw him crack a smile at the end) and Mangini...Jesus christ that man was on fire, his drumming was spot on, and I have never been more amazed by a drum solo in my entire life. But you know what was the best thing? They were having an amazing time. Petrucci actually went 'wow' when he saw the crowd, and Mangini was laughing and smiling and it was infectious.
Oh, and James managed to get 30 odd thousand people fist pumping like guidos.
Oh, and my throat kills from singing along to all the songs.
TL;DR: Dream Theater are great live.
