''Coming soonThe setup for this tour was minimal with basic lighting and fog machines. There was also a gate-like structure made from metal pipe that went across the stage, separating the drum riser area from the rest of the band. A lighting truss was set up at the front of the stage, from which was hung three chains, much like the ropes that hung down during the [[Hate Tour]].''
