I went to see Nothing of Consequence (www.nothingofconsequence.com) play a show at a certain club downtown and I had to wonder what the hell the tech guy was doing. I could forgive the light cues since he's never heard the band play before, but why did he keep blasting that fog machine?
Typically, I've seen these things stored backstage so that the fog slowly creeps out around the band's feet and that's where it stays. What the Tech Dude was using was suspended high above the stage and would literally dump fog down on the performers. But they were real troopers.
