"I'm not talking about volume. What I feel about the Philadelphia sound is that you get this extremely homogenous sound. It comes from an extreme involvement from every player. . . . I can't say it took me by surprise, but when actually you are there experiencing to make music with that kind of sound - sound is attitude, right? And that attitude is really at the center of my conception of what I feel orchestral playing should be. And I think that is why it clicked."
