I grew up with singers. My father's mother sang opera. My dad was a big band singer. I can't remember a time there wasn't music in the house, so I grew up listening to great songwriters - George Gershwin, Cole Porter - and my grandma was playing opera for me before I was 3.

I don't have any particular methodology, to tell you the truth. 'Silver Blue' took exactly the amount of time to write that it takes to sing it, and 'Prisoner in Disguise' took about a year and a half. So you just never know.

Supplying fuel for a Mars expedition from the lunar surface is often suggested, but it's hard to make it pay off - Moon bases are expensive, and just buying more rockets to launch fuel from Earth is relatively cheap.

You make your first album, you make some money, and you feel like you still have to show face, like 'I still go to the projects.' I'm like, why? Your job is to inspire people from your neighborhood to get out. You grew up there. What makes you think it's so cool?
