As far as general crowd interaction, I don't think I've seen anything as nuts as Ceremony's set from yesterday. Non-stop stage-divers off the stage, off the amps, off each other. Lots of pitting, lots of crowd-surfing, lots of singing along. I've never seen anything like it. But I wasn't in the pit for that.
For one that I was actually in the craziness for, it was probably Origin's homecoming show a few weeks ago. I've talked about it before, and anyone at an Origin show knows what I mean.
