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 got into DJ'ing because I started to listen to New York radio a lot. Obviously, I knew the stuff everybody knew, like Beastie Boys and Public Enemy, but I heard "Who Got the Props" by Black Moon, and I went up to this kid in my school with the Walkman on and was like, "What is this? You must tell me how I can get this now." Because there was no Shazam or googling lyrics.

And I remember that about three years before that, her first record had come out. And I just remember really liking this one song off it called "In My Bed" and being a little bit enamored. This, you know, this young kind of Jewish girl from North London, you know, I have the same thing - from a Jewish family from North London - with this incredible voice.

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.

You know, it's weird. It's - it hasn't really changed my life in any kind of way that I can measure. I mean, it's obviously such an insanely amazing thing. You know, none of my other records I've ever had before even broke into the top 100.

You know, that was the first time [with Any Winehouse] that I probably ever used a baritone sax. And it's certainly the texture that, you know - it's all over the record 'cause it's a nice compliment to her tone.

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.
