Robert "Mutt" Lange, whose marriage to Shania Twain ended earlier this year, has gotten back to work as the producer for Nickelback's new album. The band will release Dark Horse on Nov. 18 on Roadrunner Records. The album was recorded both in Lange's home studio in Switzerland, as well as Vancouver, Canada, where Nickelback's Chad Kroeger has a studio. Nickelback's 2005 album, All the Right Reasons, sold more than 10 million copies worldwide. When Nickelback performed at Nashville's Sommet Center in 2007, they included a cover of Joe Nichols' "Tequila Makes Her Clothes Fall Off" as an encore.
