„For me, the most important thing is the element of chance that is built into a live performance. The very great drawback of recorded sound is the fact that it is always the same. No matter how wonderful a recording is, I know that I couldn't live with it--even of my own music--with the same nuances forever.“
— Aaron Copland American composer, composition teacher, writer, and conductor 1900 - 1990
