In Boston I sat behind probably the 6 most enthusiastic DT fans in New England. They were really into the whole show, constantly jumping around, screaming, pumping fists, etc.
Then BAI came on, and they quieted down for the first time during the show. It was weird, but I'm not complaining as it was the highlight for me and I got to see/hear more of them playing it.
After a couple of the solos they all started doing the "were not worthy" worship motions and when the song started wrapping up, they got into it again. Since they knew all the new material, I suspect that their calmer reaction for most of the song was from being in awe rather than disliking the song.
