The musicians are in these 8-foot-by-8-foot boxes with kind of a 70-percent screen on them, and they are covered on all four sides with lights inside of the boxes. You can only see them if they light up from the inside. Sometimes there are video projections on the boxes, so you don't see the whole show and you are totally relying on your ears. I use headphones more on this tour than I ever have because I can't see exactly what they are playing. I've never had to mix blind like that. They'll start off visible, then the lighting changes and they can't see each other either. They are playing strictly off of trust and vibe.
