This morning I came across a great article over at Wired.com about the current stage show on Nine Inch Nails latest tour. It is one of the most high-tech setups that has ever toured, features multiple moving “stealth screens” as well as interactive lights and video the band members can actually control on the fly.

“With the song “Only,” for instance, the front, convex screen starts out as solid static. On Reznor’s side of the display, a laser above him detects whenever he crosses a vertical plane paralleling the screen. On the floor, a piece of tape and two tiny LED lights let him know exactly where that plane is.

As Reznor intersects that plane with his hand or body, the laser tracks his X and Y coordinates. The “brain” box then tells the particles to spread out to a predetermined dispersal pattern. Reznor says: “Then it follows me around. If I leave the plane, it fills back in. If I push through, it comes back out.”

Proving that he is the ultimate professional once again, Josh Freese doesn’t just pound out beats on his DW drums, he is turning off and on a drum grid sequencer. “We recreated a grid drum sequencer,” he says. “[Drummer Josh Freese] is actually touching and turning them on and off. But he’s not really touching the screen. He’s crossing the same laser on the back screen, which gets calibrated at sound check.”

These are just a few aspects of the band’s current stage setup, the article is fairly long and well worth the read.
