"Music has no physical matter at all, it’s just waves, I guess. I don’t even know what it is. It’s just waves. And yet emotionally and psychologically it matters to us probably far more than architecture. I think people have more opinions and allegiances to songs and styles than they would to architecture, for some reason. And I don’t know why that it is, even though it doesn’t matter—like physically doesn’t have matter. It still matters more to people. It’s a mysterious thing."
