Miles Davis made music that grew from an uncanny talent to hear the future and a headstrong desire to play it. From his beginnings in the circle of modern jazz, he came to intuit new worlds of sound and challenge. While the vast majority of musicians – jazz, rock, R&B, otherwise – find the experimental charge and imperviousness of youth eventually running down, Miles forever forged ahead. In doing so, Miles became the standard bearer for successive generations of musicians, shaped the course of modern improvisational music more than a half-dozen times.
