It's been 11 years since Alkaline Trio released their first full-length album, Goddamnit. In that time, they've toured the world, sold over a million records, and expanded their sound radically beyond their original straight-ahead punk style, incorporating production slick enough to earn them mass exposure on outlets like MTV's The Hills. Now with This Addiction, their seventh album and first for Epitaph, the Chicago rockers are heading back to their roots.
