SLIPKNOT percussionist/mastermind, Shawn Crahan (a.k.a. Clown), recently explained how he went about assembling the band's "Disasterpieces" DVD, due Nov. 26 via Roadrunner."I didn't really have an outline, because the first thing was, you know, let's check out what we have," he said. "So, I watched all the footage. I watched it all, man. I don't think anybody believed me that I was going to do that, but I did. So I went. That's what I do. I mold. I look for 'the fuck.' I call it 'the fuck.' I look for those things that makes me taste and smell and gets me excited. I look for those things to start it off, and once I have a few of those then I get going. And then the plot goes from there." More than two hours of footage are included on the double-disc DVD. The band's London Arena performance filmed on February 16, 2002 is featured, as are five music videos, including the animated version of "Wait & Bleed" and the banned video for "Spit It Out". It also contains behind-the-scenes footage.
