Metallica guitarist Kirk Hammett recently took a defensive stance towards "Lulu" collaboration record, ranking it among the band's top-quality efforts. As Hammett told the Verge, exploring the uncharted waters still comes as one of Metallica's top priorities, regardless of what the fans might think. "We're doing it for ourselves, man," he explained. "'Lulu' is a really good example. I think that 'Lulu' is some of the best stuff we've done. I mean the song 'Junior Dad' moves me to tears, and working with Lou Reed was such a cool, unique, and special thing for us." However, the axeman did agree that the album isn't exactly too approachable. "Maybe it's not for everyone," he added. "Maybe it's a challenge for our fans, but for us - Lars, James, Rob, and myself - we loved doing it and it was such a great experience. We look back at it very positively." Kirk already pointed out that fans aren't remotely close to anyone's mind during the Metallica creative process. This of course wasn't a jab at the listeners, but a way to stress how things work among the ranks of metal titans. During the rest of the chat, Hammett drew an interesting parallel between the way modern musicians make a living and how things worked in the music world a century ago. "It's ironic in that with the advent of this technology, making a living as a musician has kind of gone backwards," he noted. "You can't just make records and expect to sell them and live off that. If you really want to make a living making music, you have to go out there and play, and perform, which is just how it was 100 years ago!" As the guitarist further explained, technology is making musicians work harder, but is in a way killing the community aspect of the music. "I'm sure there’s still a lot of great art being made out there, but it's not the same," he said. "People don't rally behind it, there isn't a community behind it. How are people supposed to let other people really bond, how are people supposed to bond behind bands like they used to? It's just not there. It's all separate now, all in the name of convenience. That's just the way it is." When it comes to the new studio record, Kirk wasn't very vocal. Apart from confessing that the band would probably be half way through it without "Through the Never" 3D film, he once again confirmed that the four-piece will enter the full work mode at the beginning of 2014. Metallica recently posted an official recap video of their Rock in Rio 2013 festival performance.
