Miles Davis – The CBS Years 1955 - 1985

Nice choices, nice mastering and pressing
interestingly the booklet features a photo of the March 1978 "Miss Last Summer" studio session mistakenly stating that Elana Steinberg-Cob is Flora Purim.
the "Electric" category is pretty self explanatory
the "moods" disc is a nice selection mostly from the Post Bop /Second Great Quintet period

the choices from the much maligned 80's are mostly strong, the Startling "What It Is" shows just how aggressively strange Miles music still was in a period often lazily referred to as "pop"
Ms. Morrisine features the great John McLaughlin on guitar giving it a connection back to the earlier material
This package would seem to contain some unique remixes of the early acoustic material but as a fan of primarily the 67-75 material I am not in a position to confirm the uniqueness of these mixes.

update July 2020: Sivad seems to be the Quadrophonic version, not listed as such but leaps out of my speakers in that way only quad LPs can. Also, the release date listed on the box is the date of the Quad release in 1972 not the original 1971 stereo release
