I originally wanted to embrace the imagery and forthrightness of rap music. There are some interesting, dynamic voices in rap. But I find most of it irresponsible in its overt violence and commercialization of anger. As artists, we believe we can will action through language. If that's the case, we have to take responsibility for what we say.

Writing is the hardest work in the world. I have been a bricklayer and a truck driver, and I tell you – as if you haven't been told a million times already – that writing is harder. Lonelier. And nobler and more enriching.

It helps me to learn things in different languages, even if it's just phonetically, and to make myself vulnerable to other audiences by trying to reflect back to them the genius of their own cultures, and to do that, oftentimes, in new jazz settings, new arrangements. It's a way to show respect.

After years of doing composition, the risk is always that you might start to repeat and be cliche. Every time, I try find a way to be reborn again as an artist. Its not easy to reinvent yourself every time, as it takes a lot of creative energy, but I am happy to do it.

I can't think of anything worse, really, than to try to live up to someone else's expectations of what you should be. You don't make art by consensus.

Hollywood is a very volatile place where artists come in, and they essentially say they want to belong. It's incredibly vulnerable to be an actor and also get criticism at a young age when you're formulating who you are. We've seen a lot of people fall victim to that, and it's very unfortunate.
