A lot of comment on the seating (or non-seating) choice by the band. For me, it depends. As I've gotten older, I prefer having seats. I'm short, so I continually deal with tall people being in front of me regardless of the configuration.
I firmly believe that GA configs provide a lot more energy. But for those that are saying that DT is a metal show -- they used to be. In the 90s. They aren't any longer. For those who feel this way - I'm with ya. Seeing SFAM from seats (albeit I was standing the whole time) was sorta...lame. Mosh pits were necessary at points, and there were none. When I saw it performed on Feb. 26, 2000, in NYC at Roseland, my only memory that remains was during "Home," where the entire audience had so much energy, that I literally was picked up off my feet (still vertical) and transported to the other side of the venue. It was both an incredible and scary feeling. But there was SO. MUCH. ENERGY.
These days, while that energy is lacking a bit, I absolutely see the safety concerns involved, and the shift in audience a bit (a lot of us old metal dudes are old now - ha ha).
But DT has evolved to become more of a metal opera kind of band whose audiences are less full-on metal, and more very technical and progressive driven (at least to my observation). So it makes sense. Sort of like how Savatage evolved into TSO essentially. So, I get it. Either way, its still a great show, and if DT prefers seated options when available, that's their choice. It doesn't bother me either way (although admittedly, my legs are killing me because I HAD to stand the entire time because of people in front of me on Sunday night - hahahaha).
