“But it is the moment when something appears as if out of nowhere, when a work of art carries within itself the thrill of invention, of discovery, that is worth listening for. It’s that moment when a song or a performance is its own manifesto, issuing its own demands on life in its own, new language—which, though the charge of novelty is its essence, is immediately grasped by any number of people who will swear they never heard anything like it before—that speaks. In rock ’n’ roll, this is a moment that, in historical time, is repeated again and again, until, as culture, it defines the art itself.”
