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.

Sharing's only fun when it's not your stuff.

Hugh [Evans] called us. And obviously this has been on our radar for all the years it`s been going on. And each year obviously reaches more and more people, and it`s high profile. Hugh reached out to our manager just down the street. And we said we`re here [ on GLOBAL CITIZEN in the Central Park] to help and do whatever we can.

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.

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.

I really like LIMP BIZKIT. I mean, I've said it for years - I don't know if anyone actually hears it - but I think LIMP BIZKIT are an awesome band. In terms of the rap-rock bands, or ANY bands out there, I think they really are truly among the best.
