I went to see it with a friend of mine. I have to say it was one of the greatest and most over the top concert I've ever been to. With every drumbeat, the entire arena shook. Amazingly bright lights were everywhere. 20ft. high flames shot up from a giant column not too far from where I was sitting. Flames on the stage changed from red to blue to green. They played everything that they could think of I think. Everything from Beethoven's 5th to Rollin on the River. The songs were very powerful and epic. The music and the visuals matched perfectly. Nothing I can type can express just how amazing it truly was. If you ever get a chance to go to one of their concerts, go.
Funny Note: All the guys in the thing had long hair, except for one bald guy.
