Metallica drummer Lars Ulrich isn't kidding when he says "everything we do is always documented."
When the band played its first-ever China concerts last week, the cameras were rolling -- and some of the footage, according to Ulrich, might end up "bridging" into Metallica's upcoming 3D film, Through the Never .
"We think that there is something cool that will come out of [this]," Ulrich added during a press conference held this past Wednesday 14 in Shanghai. "Whatever that is, we're not quite sure yet, but we'll do our best to make it shareable and worth everybody's while."
Ulrich also noted how "emotionally engaged" the fans in China had been during Metallica's visit to Shanghai for two sold-out shows at the Mercedes-Benz Arena on Tuesday and Wednesday.
"Obviously, there is a language barrier," Ulrich said. "What we try to do, we try to loosen the moment with banter and so on, and some of that doesn't seem to translate when there's language issues or whatever. But you can feel that there is a passion, and that there's been a longing for this moment that is really special."
