Miles Davis revolutionized jazz in the 1950s by refusing to stay in one place musically. His albums with arranger Gil Evans and his first great quintet established him as a bandleader willing to chase new sounds rather than defend old ones. Davis had an ear for what was coming next, and he surrounded himself with musicians sharp enough to follow him there.
As a trumpeter, Davis was economical. He didn't play every note; he played the ones that mattered. This restraint became his signature across bebop, cool jazz, modal jazz, and eventually fusion. His influence extended far beyond jazz clubs into how musicians of every genre think about space, timing, and the power of what you don't play.
