The masked Iowan nu-metal nonet's fifth studio album, and the follow-up to 2008's All Hope Is Gone. It is the first to feature their new rhythm section, following the departure of drummer Joey Jordison and the untimely death of bassist Paul Gray. Marking a return to a more raw, brutal, dissonant sound reminiscent of their earlier work, the album includes the singles "The Negative One" and "The Devil in I."
