According to The Pulse Of Radio, SLIPKNOT percussionist Shawn "Clown" Crahan says that he's been thinking more and more lately about the possibility of eventually retiring from performing with the band, and says that if he does, his 18-year-old son would be the perfect replacement. "My oldest boy, when I do skip, he's gonna take over my slot," he said. "He was sitting on the stair in diapers wearing my mask with sticks while we were downstairs trying to learn how to be a band. So when I leave, it won't be like I died and my son came in and tried to fill my place. I'm gonna bail, but I'm gonna hand over the throne and say, 'Hey, I can't do it anymore. You do it. You're my blood.'"

Crahan has four children with Chantal, his wife of 20 years. Their 21-year-old daughter Alexandria works with her father on SLIPKNOT.

They also have a 15-year-old daughter named Gabrielle and an eight-year-old son named Simon.

As previously reported, SLIPKNOT will make its Blu-ray debut on July 31 with the release of "{sic}nesses: Live At Download".

Filmed in high-definition and newly remixed in digital surround audio, the disc captures SLIPKNOT's June 13, 2009 performance at England's Download festival, an 18-song, 159-minute show in front of 80,000 music fans.

Included is a 45-minute documentary directed by Crahan as well as four music videos. The set was originally released on DVD in 2010.

SLIPKNOT is currently co-headlining the Rockstar Energy Drink Mayhem Festival tour, which stops in St. Louis on Friday (July 20).
