Thanks fro posting.
I saw them play in Detroit and I posted this before how they just plowed through their set with very little interaction. This is polar opposite of how they interacted with the Detroit fans and IMO Detroit fans were more into the show than these folks in Boston. Maybe knowing they were being filmed helped?
They didn't know about the filming until after. (I was originally going to shoot photos.) But they said we were the loudest crowd of the tour, so maybe that helped invigorate them.
