Every yin has its yang, every north has its south. And so it was with the frenetic, hyper-energetic style of Bebop, which was followed by what we now call 'cool' jazz. The term started to be applied to a new school of jazz in the early 1950s, when Capitol Records released the album Classics in Jazz: Cool and Quiet. But many people associate the nascent cool movement by the uber-cool master of jazz, Miles Davis. He even named one of his albums 'The Birth of the Cool' and it’s an iconic album that stands as a milestone in the history of jazz to this day. He was quickly followed by musicians such as John Lewis’ Modern Jazz Quartet, Gerry Mulligan, Bob Brookmeyer, Stan Getz, Chet Baker and George Shearing.
