Disturbed will kick off their US tour with a series of headlining dates starting April 26th before taking their brand of pummeling metal and dynamic hard rock on the road as part of the "Mayhem Tour." The mega-package tour, conceived by "Warped Tour" founder, Kevin Lyman, and his "Taste of Chaos" partner, John Reese, will start in July and find Disturbed sharing a stage with Slipknot, Dragonforce, Mastodon and several other heavy hitters!

Excited to get their new music out to their fans, they've also posted the scorching, "Perfect Insanity" as a free download on their official website (disturbed1.com). This is a re-worked, much heavier version of a song the band recorded early in their career. But you can also check out the first single, "Inside The Fire," - right here
