I have written most of my melodies walking and I feel it is definitely one of the most helpful ways of sewing all of the different things in your life together and seeing the whole picture.

I'm a fountain of blood in the shape of a girl . . . leave me now return tonight tide will show you the way if you forget my name you will go astray like a killer whale trapped in a bay

I've written arrangements for choirs and strings in the past, but I usually write music with my voice or a keyboard and then I'll get someone who is good at writing scores to write it out. Or, if I have the luxury of time, I will go in a room and hear the people perform and then change it through what I hear, not on paper. I can read music OK, but I probably rebelled a little - music changes into something else when you read it.

The reason I do photographs is to help people understand my music, so it's very important that I am the same, emotionally, in the photographs as in the music. Most people's eyes are much better developed than their ears. If they see a certain emotion in the photograph, then they'll understand the music.

But I'm not interested in politics. I lose interest the microsecond it ceases to be emotional, when something becomes a political movement. What I'm interested in is emotions.

Solar power, wind power, the way forward is to collaborate with nature - it's the only way we are going to get to the other end of the 21st century.

It's invisible, what women do. It's not rewarded as much.
