Gary Graff of Billboard.com reports: Heavy, dark and "pissed-off" are the operative terms for DISTURBED's new album, according to frontman David Draiman. Draiman tells Billboard.com that the quartet is about 12 songs into the set, which DISTURBED is producing itself in Chicago.Tentatively titled "Indestructible", it's due out in the spring of 2008 via Warner Bros. "We're probably going to track 15 (songs), and we'll put 12 on the record," Draiman says. The album's tone, he adds, is directly inspired by "a f*cked-up couple of years" in his personal life — including a motorcycle accident, a garage fire that destroyed his truck and motorcycle, and "a number of bad relationships." "When we first discussed what we were going to be shooting for, vibe-wise, on the record," Draiman recalls, "I said, 'Guys, listen, my head is in a really in a f*cked-up place. Give me the nastiest, darkest, most brutal sh*t you can throw at me, and I'll write to it.'" Read more at Billboard.com.
