I felt a bit bad for the band, too, because it was finally their chance to cut loose. They were playing at the beginning of the event, but of course nobody's going to get up and dance then, just like people aren't going to buy food as soon as they arrive. It would make more sense to have the open floor in the middle of the event, so that people could get up and move around after sitting for a while, and then be content to sit some more. I got pretty restless halfway through and could have used a dance break.
