I started playing bass for the same reason everyone else does – I’m a lousy guitarist.

First and foremost, I want people on concerts to have a really great experience away from the negative press and negative stuff that you see on the news and Facebook. I don't even like seeing people's cell phones. Let's have a human experience and rub up against each other, you know.

I don't really give a f**k about the mainstream. The mainstream doesn't offer me anything. Why would I offer it anything? I love the world I have. I love the sort of subculture that Green Day represents.

I look at my kids as the Harry Potter Generation. There's a sense of justice about that, in beating Voldemort. It's a classic tale of good versus evil. To have a role model like Harry Potter that says you can defeat evil, but still be a complicated human being. That gives me a lot of hope.

I think that's the most important thing you can do to be a real person - is to be honest with yourself.

Early on I learned to question everything. But I feel like everything is so divisive right now. Going against the grain would be to not be divisive and be inclusive. That's the disruptive way to go about it.

For me, it's important to get back to fundamentally what it feels like to be an American. We all come from different backgrounds, but we come together and create this world. It's like a microcosm for the rest of the world. I want people to feel unity when they come to a show.
