For me Miles Davis has always blown high. Not for the wind, but in the clouds, the animating. Feet on the ground (some of his album and all the ways it is jazz and what the word suggests) the head in the sky. As if he was already there, just by blowing while Coltrane burns in his "climbs" in its "Supreme" quest. But times are changing and the artist (real, creators) and new cloud ridges, hills appear then are crossed. Indicates the new direction certainly wiser than my own comment: New instruments, electric: great pianos. The cream of future jazz-rock (now usually called "Fusion") is there. Atmosphere: Weather report will: Zawinul and Shorter. McLaughlin on guitar. Corea, Hancock, Holland Williams: a feather flock together, it is only ready ... geniuses. Miles is. This record proves that and the rest will be born. In another context, that of classical music, we think of a work of Dutilleux: Starry Night "Stamps, space, movement." In this context: to add electrical rhythms and sounds. A kind of blue way somehow.
