Vidal Sassoon

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.

In jazz, you listen to what the bass player is doing and what the drummer is doing, what the pianist and the guitarist is doing, and then you play something that compliments that, so you are thinking simultaneously and thinking ahead.
