"[Some] times I'd have sound but no image. When Patti [Smith] was singing with her guitar, or doing something amazing with her clarinet, I'd just mess around and record the sound. So we'd use those sounds as another layer in the film [Dream of Life]."

It is possible to enjoy the Mozart concerto without being able to play the clarinet. In fact, you can learn to be an expert connoisseur of music without being able to play a note on any instrument. Of course, music would come to a halt if nobody ever learned to play it. But if everybody grew up thinking that music was synonymous with playing it, think how relatively impoverished many lives would be. Couldn't we learn to think of science in the same way?
