Nearly a decade after the release of their groundbreaking debut, "The Sickness," Disturbed have become one of the most respected bands in the hard-rock universe thanks not only to pummeling riffs and jackhammer beats but passionate insights into our troubled times. Three platinum-plus albums - "Believe" and "Ten Thousand Fists," charted #1 - have led to "Indestructible," the group's darkest, angriest outing yet.
