What I look for in musicians is a sense of infinity.

I don't know if I would qualify as mainstream. I think I have managed to function pretty successfully on the fringes of the music world and have been able to play exactly what I have wanted the way I have wanted.

It's more about conception and touch and spirit and soul than whether my hardware was in place.

I have three young kids and a great family. I love hanging out with them more than anything.

I guess with any type of music or any art, there's always an evolution.

One of the things I had to learn as a writer was to trust the act of writing. To put myself in the position of writing to find out what I was writing. I did that with 'World's Fair,' as with all of them. The inventions of the book come as discoveries.

I started to understand that for me, art was no longer about self-expression but about creative engagement with the world. I started to respond in an excited way to making work inside an industry and not feeling the constraints of audience expectation as some kind of thing that I should avoid.

Even before Pentatonix, I always thought that I would be out here in New York doing Broadway and doing musical theater. That was what gave me the passion for music in the first place, so it's been really, really, cool.
