And music is kind of a - it's like a finicky industry to be in of course. Like, tastes change. You're hot one minute; you're not - you know, I've been through it quite a few times, like, on both sides of it.

So sometimes if I'm working with a rapper, like Ghostface Killah or Nas, producing usually means, in hip-hop, that you make the music. You make the beat, and you give it to them. And they write the rhymes.

You have to put these hooks in it, you know? You've got to make sure you got all that ear candy in it to get it through the gate.

I think that where it came from and the initial birth of it - it did come out of a jam at Bruno's studio, you know? He was playing drums. And Jeff Bhasker, who co-produced the record with us, is on synths, and I was playing bass.

I didn't really get that good at cutting because I didn't have those three years of gestating and nurturing my skills in the bedroom. I was kind of, like, out and playing in clubs after three of four months, because I was pushy with promoters. But I would just listen to the radio - Stretch Armstrong and Red Alert - and then I would go hang out with Mayhem, who did the WNYU hip-hop show.

Basically, there's a good friend of mine who works at EMI Publishing, a publishing company. He had asked me - he was like, you know, do you know this girl, Amy Winehouse? She's in New York for a day. She's kind of meeting people to maybe work with on her second album.

So when I was working with Amy Winehouse on "Back To Black," you know, she had all these beautiful songs, incredibly well-written and just her on an acoustic, nylon-string guitar. And she'd play them for me, and then I would kind of drum up my idea of what I thought - make a demo with what I thought the drums should be doing, the guitars - like, quite a crude demo.
