I'm just sittin here trying not to be unhappy.

Parenting changes your life, it changes how you hear yourself in relationship to others - which is part of the reason that a bunch of people in the rock community are sick of the goodwill and positive energy and love between these 45-year-old musicians who they preferred when they were 25 and taking stabs at each other.

Some people try and tell you what the songs are about and it bores me to death.

As long as it says Metallica on the record it's Metallica.

Doing things the way you see it, going by your own heart and soul, that is pure artistic integrity. Whether the hair is six or sixty inches long, the eyes have make-up or not, the riffs are in 'E' or 'F' sharp, the amps are Marshall or not, all those things don't matter if you are doing it for the right reason, which to me means doing it for yourself!!

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.

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.
