In a recent interview with Rolling Stone magazine, METALLICA drummer Lars Ulrich was asked how long he thinks METALLICA can continue to make music and tour. "METALLICA will go on forever," Ulrich declared, "bar the $64,000 question. "The physical part."He continued, "THE ROLLING STONES, BLACK SABBATH, AEROSMITH — I have nothing but respect for their longevity, but Charlie Watts is not playing 'Damage, Inc.' three times a week or playing 'Whiplash' every night. This has the potential to go on for a long time. But if somebody's arm, back or neck just says, 'Fuck this,' and quits, I don't know. "I could be content without it when it's time to say, 'Dude, that was crazy, now it's getting a little silly.' I know some people already think it's a joke. We don't — yet." METALLICA guitarist/vocalist James Hetfield: "I don't know what the future holds. The fact that we've been together this long — there's a meaning behind that. We willed this to happen. It was a combination — the drive, the smarts, the right people." He added, "Listen, what else am I going to do? That's a scary thought. I think we'd all be OK if we ventured out on our own. But I don't want to lose this." Go behind the scenes of the photo shoot for the cover of Rolling Stone magazine at this location (video).
