Kind of Blue
As parts of "Jazz Track" and "Jazz at the Plaza", respectively, the "'58 Sessions" chronicled the transition from the brawny agitation of "Milestones", to the cerebral tranquility of "Kind of Blue". The recording sessions also became known as a stepping stone in Davis' move from bebop to modal jazz. The live side in particular was seen by critics as a glimpse at the sextet that would record "Kind of Blue". The complimentary and seemingly spontaneous style of performance ethic and the relationship between Davis and his musicians was fundamental for his work during these sessions and improved onto the "Kind of Blue" sessions.
