Someone else did rapid fire thoughts, so I'll do one as well:
1.) The Claw was not as huge as I imagined . It's really wide, but I thought it would be taller.
I think that's because it was at Fedex Field, the largest NFL stadium, which is very tall. It is really impressive and a great feat of engineering though.
2.) The inner circle seemed to empty a little after Muse (Muse fans leaving?). So, I got a pretty decent spot in there, after walking over from RZ1. Some of the more prime spots of the inner circle resemble a crowded Tokyo subway car. I don't see how one can enjoy the music in those conditions.
Too many distractions from people talking, walking past, tapping you to move, etc.
3.) The acoustics were so-so. There was too much reverb and echo I thought.
4.)RZ got a little crowded later on. The bridges did stop there a few times, and band members walked by. It was nice to have basically a "all-floor" access pass (i.e. RZ wristband). It is nice to have a seat in there, which I used before U2 and during One.
5.)Some people won inner circle wristbands, and some people had something called a "Day Pass" badge (in the circle). I hadn't heard of those before.
6.)Songs like Elevation and Vertigo aren't loved in the setlist parties. But they really get the crowd on their feet and singing and cheering.
7.)The band members seem to "speed walk" a lot on the circle. Slow down a bit, guys
.
8.) Not too many people seemed to be singing along in the side part of the circle. The middle part was a different story.
9.) The "no camera" policy seemed to work - only 10% of fans had point-and-shoots. I brought in mine.
10.) Fedex field has a lot of room for improvement in all areas for putting on a concert. They should stick to football.
11.) It was great to see people on their feet and with their arms in the air from the front row all the way to the furthest nosebleeds away all-around.
12.) After the show, the crew doesn't waste a single minute in starting the tear-down. They did a lot in just a few minutes.
