Disturbed began building Asylum as soon as they got off the road in the summer of 2009. Officially entering Groovemaster Studios in February 2010, the band set about self-producing the album, as they did with Indestructible. Each CD includes a card to access exclusive download or stream of the documentary "Decade of Disturbed" that recalls ten years of history in the most candid of ways. It takes you through years of countless tours, dedication and sacrifice stripping away all the gloss and letting the real story be told... the documentary is about the fans and their brotherhood that has been formed with the band.

2011 release, the first ever B-sides collection from the American Hard Rock/Metal crew. The set includes a previously unreleased track, "Mine," and "3," which was released exclusively on the band's website in April. Other tracks include "God of the Mind" and "A Welcome Burden," which appeared on the 2010 reissue of the band's 2000 debut album The Sickness; "Monster," "Two Worlds," and "Sickened," which were included as bonus tracks on the UK tour edition of Ten Thousand Fists; "Run," which was featured on a limited-edition version of 2008's Indestructible; and "Parasite," which appeared on the Japanese edition of Indestructible.
