Disturbed have entered a Chicago studio to begin recording their fourth album. The follow-up to 2005's platinum-certified "Ten Thousand Fists" bears the working title "Indestructible" and will be released in the spring of 2008 via Reprise Records.

According to vocalist David Draiman, the upcoming effort he and his colleagues Dan Donegan (guitar), Mike Wengren (drums) and John Moyer (bass) are creating "seems to have taken on a darker character than the previous albums. It's more furiously paced and complex."
