Nearly a decade after the release of their groundbreaking debut, The Sickness, Disturbed have become one of the most passionate and well-respected bands in the hard-rock universe, a dependable source not only of pummelling riffs and jackhammer beats, but of personal and political insights into our troubled times.

A self-produced effort, 'Indestructible' is the first Disturbed album that did not feature Johnny K, the producer of Disturbed's previous three albums, 'The Sickness,' 'Believe,' and 'Ten Thousand Fists.' 'Indestructible' was recorded at Groovemaster Studios in Chicago, Illinois. The album features two songs, "Perfect Insanity" and "Divide" that were written by Disturbed prior to their first album, 'The Sickness,' but were never previously released.
