My dad photographed a lot of beautiful dancers. My mom was a dancer.
In 1979, I moved to England and photographed Joy Division and Bowie and Beefheart. At that time I got images that I felt had that special, well - power is a big word to say - more like intimacy and ambition that outlasted the photo shoot. I felt that they would have a longer life.
