It’s Kind Of Blue by Miles Davis, first released in 1959.  It still sells more per year than any current jazz recordings.   Why?  And why do critics also rate it as one of the best albums of all time?  I quote a few critics and musicologists, play 4 of the 5 tracks, a couple other renditions of the tunes, and throw in a few pieces of irrelevant but interesting tidbits.
