My style of playing is more enthusiasm and instinct than skill.

At the beginning of my career I was going through a really weird phase of dressing in boys clothes. I would only wear one American Apparel T-shirt and shorts and brogues the whole year round. Not the same T-shirt, obviously, but one style of American Apparel T-shirt. I think I was going through a tomboy stage.

I wanted to be a witch when I was a kid. I was obsessed with witchcraft. At school, me and my two friends had these spell books; I always wanted a more magical reality. I had a little shrine at home and I did a spell to try and make the boy in the other class fall in love with me.

It’s good to be vulnerable in amongst the grandeur; you shouldn’t lose that sense of intimacy and vulnerability with people.

I'd gone from being this art student messing about with music to this girl with a record deal, magazine front covers and all this hype. In many ways, it was everything I ever wanted, but when it happened all I felt was total, paralysing fear.

I think I should get a bigger between-the-song persona, so then I'm not wandering around the stage like some mad old auntie that's saying hello to people and falling over.

When I first started, especially because I got the Critics' Choice before I'd released an album, there was a lot of scrutiny on what my character was, what my background was, what colour my hair was. I fought quite hard for the music to overtake the personality aspect.
