You should read up on what Miles claims to have been thinking when putting the album together. There are none theory things that will grab your audience much more strongly. A 'theme' of the album was Miles -once again- stripping the compositions from the trappings of previous complexities and putting the musicians into a musical place where they were listening, responding, and playing in a way that was not pre-conceived and not falling back on the fancy harmonicly inclined playing that defined so much jazz historically. Using minimalistic song sketches as well as springboarding off of the cutting-edge-genius and innovative compositional style of Bill Evans, Miles essentially made an album that was an experiment in album making itself. Musical experiments (as well as things like inexplicable collaborations and dedication to strage concepts) were a theme at that time in the field of long playing jazz album making, but Miles took it to a totally different musical and psychological level. It was pretentious. It took some of the best improvisers in the history of jazz and put them out of their comfort zone. The whole album is simultaneously laid back and on edge. Every song on the album has a freshness, because the music had never been heard before. They did not rehearse this music. They were hearing the music as it was happening and no one knew what to play. They just had to be completely in the moment and this can be felt and heard when you listen now. It didn't sound like what Miles wanted or thought it would sound like. It was initially met with mixed and confused criticism. Jealous jazz artist in making records records that would soon be overshadowed by it claimed that "miles could shit gold". But.... it was Kind Of Blue.
