In a new interview with the London Metro, Metallica drummer Lars Ulrich has shed some light on the band’s success, stating that the band's continued popularity comes from their independence. "Metallica exist in our own bubble. We're not part of a genre, we're not part of a wave, we're not part of a moment. We're completely financially independent. We own all our own records. We own all our own masters. We financed this film by ourselves. We don’t have to suck up to anybody or deal with the man. We just live in our own little world. We're our own entity, completely autonomous. And that's a very unusual situation to be in.
"It's a place we don't take for granted and we’re very aware of the luxury of being in that position. And with that comes a desire to want to always be the best and give back as much as possible without selling out. But we've put way too much money into this film (the band's upcoming concert documentary "Through the Never") in the past couple of years. If I told you how much, I'd probably have to kill myself." Ulrich also mused on the prospect of retirement, noting that he inspired to keep playing by the Rolling Stones drummer Charile Watts. I saw the Stones last Sunday and Charlie Watts is 72, and it inspired me to keep going. The hardest thing is the physicality of it. The two hardest working people in the Metallica organisation are the two who massage us every night after each show. That is a gig you would not wish on anybody. We'll see how long they can keep stitching us together but so far, so good."
