“Rhythm is everything pertaining to the duration of energy. The quality of a man’s life depends upon the rhythmic structure he is able to impose upon the input and output of energy. Energy equals mass times the speed of light squared. Einstein understood what Thoreau meant when he spoke of men hearing “different drummers.” Thoreau did not say saxophonists or harpsichordists or kazoo players, mind you, but drummers. The drummer deals almost exclusively with rhythm, therefore he is an architect of energy. Art is not eternal. Only energy is eternal. The drum is to infinity what the butterfly is to zero.”
