Lamb of God were set to kick off a run of North American tour dates with Slayer in Gilford, New Hampshire last night (July 26th) but with just hours left before the show began, the band announced that drummer Chris Adler will be sitting out the entire tour due to “unforeseen circumstances.” Prong and Winds of Plague drummer Art Cruz has been hired to fill in for Adler, per his own request. The second leg of Slayer’s farewell tour, featuring Anthrax, Testament, and Napalm Death, is set to run through August 26th. Lamb of God said that Adler would be back soon, writing: “We expect to see Chris returning in the very near future. We will see you all on the road soon.”
