According to Kerrang! magazine, SLIPKNOT was nearly forced to cancel its video shoot yesterday (June 30) due to DJ Sid Wilson being hospitalized with a head injury.The band delayed filming of the promo clip for "Psychosocial", the first single from SLIPKNOT's upcoming fourth studio album, "All Hope Is Gone", after Wilson managed to knock himself out BEFORE arriving on set. Percussionist Shawn "The Clown" Crahan told Kerrang!: "Sid's building himself a studio downtown and got attacked by a door knob. Now he's got five staples in his head." "Psychosocial" is available for streaming in its entirety on Spinner.com. "Psychosocial" made its way to radio stations yesterday (June 30) and has now been made available for digital download. SLIPKNOT has tapped Colin Richardson (MACHINE HEAD, FEAR FACTORY, BULLET FOR MY VALENTINE, NAPALM DEATH) to mix "All Hope is Gone". Due on August 26 via Roadrunner Records, the disc was recorded with producer Dave Fortman (EVANESCENCE, MUDVAYNE) at a studio near the band's hometown of Des Moines, Iowa. The last SLIPKNOT studio album, "Vol. 3: (The Subliminal Verses)", arrived in 2004 and sold more than a million copies in the U.S. SLIPKNOT will co-headline the Rockstar Energy Mayhem tour this summer with DISTURBED. The trek, which also features DRAGONFORCE, MASTODON, MACHINE HEAD and others, kicks off on July 9 in Seattle.
