Both nights were excellent.
I tried to avoid looking at the previous set lists in advance, but it appears that there's a fair amount of overlap in terms what they play from city to city (which isn't exactly surprising, and isn't meant to sound like a criticism) so probably not a ton of variance throughout the tour.
Crowd was even mellower than I expected, but if you wanted to find a mosh pit, there were almost always a few dedicated locations on the floor where things were rowdy.
This was Doomlet's first concert, and he crapped out on attending the second night. He doesn't do very well with events of unspecified/unknown duration, and he had a busy day outside doing summer camp shit (and refused to go to bed early the night before, or sleep in the morning of the show because he knows everything...), and the process exiting Soldier Field is a complete and total shitshow, so that kind of burned him out on the experience at the end of the night.
We're all going to Iron Maiden in a couple of months, so we'll see how that goes....
