As far as people I'd like to work with, the list is endless. I think to work with Steve McQueen would be amazing, and then some of the U.K. talent we have: Eddie Marsan, Olivia Colman, both of whom I have met and admired for a long time. We're very blessed in this country; there is so much talent for people to work with and learn from.

I think the mistake lots of people make when it comes to a psychopath is that they completely write off their actions as cruel, callous and completely calculated, but actually, the truth is that they have interests and reasons behind their actions.

The bass line is the anchor for me. I started with the bass, and either doubled that and then added the harmonies, or sometimes added my own harmonies that I've always wanted to sing on the song. And then it just went on from there - singing violin parts and trumpet parts and just trying to emulate the sounds of the instruments.
