Howard Ungerleider's designs for Rush's Time Machine tour called for more special effects than the band's previous Snakes & Arrows tour. Pyrotek Special Effects' John Arrowsmith has been serving up everything from pyro and flames to cryo. "Caravan," a song on Rush's Clockwork Angels album, describes fire and flames in the lyrics. For "BU2B (Brought Up 2 Believe)," another song from the forthcoming album, the design includes eight cryogenic heads positioned upstage as part of a steampunk gag. For "Witch Hunt," Pyrotek creates a fire-burning look around the stage with Dragon devices on a low random flame setting.
