Dave Guy, the trumpet player, is an incredible musician. He came into the studio one day, and they had just cut a cover of "Sign, Seal, Deliver" for something with Sharon Jones, and I just was blown away by how they got that sonic. I mean, it was just so much the real deal.

My mother was pretty strict. I hated it, but maybe it made me a bit more sensible.

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.

It's like every time you have one of these, you're sort of - your lease is renewed another five years. And that's kind of great for me 'cause that's all I really want to be doing still at this point, like just making records and getting to work with, like, artists that I think are exciting.

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.

I never studied jazz technically; I just know and love the music.

I had a somewhat frenetic childhood because my mum and dad split up when I was five, and then my mum remarried.
