I'm pretty obsessed with Stevie Nicks from her style to her voice. I like watching her on YouTube and her old performances, the way she moves and everything.

The aesthetic came along the way, I think - just through experimenting, and going on tour, and trying stuff out on stage, having fun with it, and not taking it too seriously. If I had a ballgown at home, I'd wear it onstage. If I found something in a charity shop, I'd wear it. That's where it grew from - just wanting to play dress-up.

The release of 'Lungs' was so hard. It was terrifying, because it was the first time doing everything. The first experiences of media exposure were almost paralysing. I spent a lot of time crying on the floor of the studio - it sent me a bit mad.

I'm completely in love with the world but also terrified of it. It creates some overwhelming feelings. Wanting to battle out that joy and fear is part of my music.

I feel things in quite an intense way. I'm not actually the most intense person.

When I am with my family, then I can just sort of switch off. It's kind of weird, because I go back and I go into this bedroom that I have had since I was a teenager. It is like this parallel universe, because one minute I am on the red carpet and then the next I am hiding out in this room I have had since I was 15.

'Dog Days' was recorded with pens and the wall, and half a stolen drum kit that was out of tune, in what was basically a cupboard. The only instrument I could really play was my voice, so we just layered everything a hundred times. It was enthusiasm over skill.
