When I was growing up, albums were my closest friends, as sad as that may sound - Joy Division's 'Closer,' or Echo and the Bunnymen's 'Heaven Up Here'... I had a more intimate relationship with those records than I did with most of the people in my life.

For better or worse, I'm interested in just about everything: every different type of music I can imagine. I can never see a reason to choose just one type of music at the exclusion of everything else. Different types of music are capable of being rewarding in different kinds of ways.

When I tour I'm going to countries to play music for people. My presence in a country is not an endorsement or a condemnation of that country's policies. My presence in a country is an effort to connect with people through playing music.

I've worked with all sorts of random people - everybody from Metallica to Britney Spears to Ozzy Osbourne to Michael Jackson to the Beastie Boys. I've got a really strange CV. It's interesting - I work with a lot of these disparate, different people to learn what it's like to work with random people.

There are so many causes. Gun control, climate change, deforestation, animal welfare, human welfare, education. Working on the big issues is noble and great, but being aware of what’s going on around you right at this moment, being kind to the people around you, extending compassion and decency, not just to everyone you meet but also to yourself—I think that’s one of the biggest challenges most people face.

Sacha Baron Cohen is one of my heroes.

I love lots of different types of music, but it's music that has this up-swelling of beauty and emotion that is most important to me.
