I love to sing old Motown songs to myself, or some Patti Smith Edith Piaf or Billie Holiday. That gets me in the mood for singing.
I don't start a piece knowing exactly what effect it's going to have. There is a seed of an idea that I could never articulate, right at the beginning of the piece, literally like one cell.
I'd never say I'll never have a facelift, but I'm way too scared of looking like a different person. I have no philosophical or political position on plastic surgery; I just don't want to look crazy. And I don't like not being able to tell how old someone is: It's creepy.
