KILLSWITCH ENGAGE's enigmatic guitarist Adam Dutkiewicz has been forced to leave the band in the middle of its successful run as stand-out performers on the Vans Warped Tour due to health reasons. Adam underwent back surgery in early 2007. In order to fully recover, his doctors have advised leaving the tour and continuing with daily physical therapy. The group will continue on as a four-piece, with their guitar tech Josh Mihlek filling in for Adam on select songs. After playing with this lineup on the July 31 Milwaukee and August 1 Cincinnati Warped dates, the band feels confident that this solution works well and will allow them to finish the tour.KILLSWITCH ENGAGE's video for the cover of the DIO classic "Holy Diver" has been posted on MySpace. The clip was shot in the Calistoga, California area the weekend of June 16-17 with director Brian Thompson. KILLSWITCH ENGAGE's cover of DIO's "Holy Diver" will be included on the upcoming reissue of the band's most recent album, "As Daylight Dies", which will be given the special-edition treatment on August 28. This special-edition CD/DVD will contain three videos and four previously unreleased tracks. "As Daylight Dies" has sold 266,000 copies in the United States since its November 21 release, according to Nielsen SoundScan. The CD is the follow-up to 2004's Grammy-nominated album "The End of Heartache", and 2005's gold-selling DVD "(Set This) World Ablaze".
