The physical structure of the piece is this. At the front of the stage is Sufjan, center, with two keyboards, a drum machine, four thousand pedals, and some vocal microphones. To his left is Bryce, with some guitars, five thousand pedals. Then I’m on the other side with a piano, a celeste, two keyboards, and no pedals aside from those attached to the instruments. Then, behind Sufjan, a drummer, James (whom everybody told me was raw vegan just to mess with my head) playing a standard kit augmented with MIDI-controlled pads. To his right, a string quartet, and on the other side, seven trombones. Hovering over the drums is a sixteen-foot inflatable orb covered in a sort of skin onto which various images are projected. There are also what look like prison lights surrounding the musicians. If you want to see videos of this, they’re all over YouTube; the ones I’ve seen are, I think, the handiwork of Sufjan Superfjans and therefore tend to be very close-up footage of his eyeball but you can hear relatively well.
