In 1958, Miles Davis was one of many jazz musicians growing dissatisfied with
bebop, seeing its increasingly complex
chord changes as hindering musical creativity. Five years earlier, jazz pianist, composer and theorist
George Russell published his
Lydian Chromatic Concept of Tonal Organization (1953), which offered an alternative to the practice of
musical improvisation based on chords. Abandoning the traditional major and minor
key relationships of
classical music, Russell developed a new formulation using
musical scales, or a series of scales, for improvisations. In contrast to the conventional method of composing during the time, modal compositions were to be written as a series of sketches in which each performer is given a set of scales that defines the
parameters of their improvisation. Modal composition, with its reliance on musical scales and
modes, represented, as Davis called it, Influenced by Russell's ideas, Davis implemented his first modal composition with the title track of
Milestones (1958), which was based on two modes, recorded in April of that year. Instead of soloing in the straight, conventional, melodic way, Davis's new style of improvisation featured rapid
mode and scale changes played against sparse chord changes. During one of these sessions, an incident occurred between Davis and Garland when he was playing piano on the song "Sid's Ahead". Apparently, Davis leaned over his pianist's shoulder, commenting on his piano playing. What was said by Davis is still unknown, but it was enough to make Garland leave the studio, leaving Davis to play piano on the track and straining the friendship between the two musicians. While Davis was fascinated and taken with the new sound Evans brought and the challenges it inspired, the remainder of the band, including Julian "Cannonball" Adderley, preferred Garland's harder, more rhythmic sound. In a 1960 column for
Down Beat, Adderley elaborated on his initial reaction to the change, stating "Especially when he started to use Bill Evans, Miles changed his style from very hard to a softer approach. Bill was brilliant in other areas, but he couldn't make the real things come off." Despite his preference for a harder piano style, Adderley opened up to the new sound. He later used Bill Evans on a July 1958 session for his
Portrait of Cannonball LP. Evans' unique piano sound and Davis' experiments with modal jazz would culminate on the '
58 Sessions. Documented in a studio session from May 1958 at Columbia's 30th Street Studio and a live gig at the
Plaza Hotel's Persian Room in September of that same year, these sessions marked the advent of Davis' new sextet, during what had already become a pivotal year for Davis. ==Music==
