Back then, I was really into composing the entire solo, beginning to end. I wanted to have it at least 80 to 90 percent complete before going into the studio. I didn't improvise in the studio. I was young, and I didn't really have the development in my playing or the ability to show up with nothing and then put down 500 ideas. I can do that now because I'm so much more of a musician now.

As the world gets smaller and communication spreads further and further out there, you try to find the right balance.

Metallica lives in a little bubble. We just do our own thing. We're not part of any trends or waves or fads. We can just do our own thing, all the time. It's a great luxury. I don't think we were really appreciative of it until recently, and really understood that it is what keeps us alive. It's great to be able to have the freedom to run around and do all this crazy stuff, and at all cost, avoid making another record, just to piss our managers off.

One of my few shortcomings is that I can't predict the future.

I would say [Lamar] Kendrick, it`s always fun to see what happens when Kendrick takes the stage. And my two oldest kids are huge fans of him.

What Metallica always tries to do, as we go around and play a lot of the same cities, over and over again, year after year, is to give a different experience. We try to never play the same venues, or if we play indoors, we'll play outdoors, and all that type of stuff. It's always about just trying to do a different kind of experience.

If there was no Black Sabbath, I could still possibly be a morning newspaper delivery boy. No fun.
