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.
I believe that music in itself heals and that everything is about the power of the mind. I thought if you are happy you don't get ill. Your health is in your head. When you are satisfied with your work you don't get ill.
