I spent my 16th birthday high as a kite, jumping out of a tree topless in my local park just because it felt amazing hitting the ground.

'Spectrum' is in part a disco song. But we play it hard, and it's a real euphoric, wailing tune. It's kind of like a total house anthem, in a way, but it seems to be going down really well. We've got all the grunge kids going mad for disco house raves.

I got to live out my 11-year-old fantasies - I got to go on stage with Green Day. Billie Joe called my name from the stage. 'Dookie' was the first album I ever bought. I covered the whole of 'Nimrod' and he'd heard it. That was like the 11-year-old girl dreamed.

I can’t worry too much about the everyday things. Otherwise I’d lose touch with my own world, that helps me as an artist, but it’s frustrating for the people around me. I’m vaguely functional, but there’s always something slightly off.

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.

Everything has such order and everyone is so focused on doing what they're doing that no one ever pays attention to you spinning and dancing around supermarkets. It's something you find in places like supermarkets and airports, where everything is really ordered. There's something about those places that makes you feel really anonymous.

I was having a conversation with my father and he was talking about this thing - strangeness and charm. It's actually the name of the two smallest particles that there are when you split the atom, so I wrote a song around it. I even managed to fit the word 'hydrogen' in there. Isn't that a nice thing for scientists to call them though?
