Music/Musical - Andrew Hill, a great and even groundbreaking composer and pianist exhibited a determined command of his materials, however abstract they might sometimes be. His composed melodies were labyrinthine, rhythmically and harmonically complex tunes that exhibit a sophistication born of mastery, not chance or contingency. As a pianist, Hill had a flowing melodicism and an elastic sense of time. Like his composing, Hill's playing had an ever-present air of spontaneity and was almost completely devoid of cliche.
