I love “Kind of Blue,” and I know what you mean when you say “there is only one ‘Kind of Blue'”–that there is only one official album by Miles Davis with that title, etc. And, that’s the thing we grab when we grab the LP or CD.

But, in another sense, there are hundreds of variants of “Kind of Blue” (performed by Miles Davis, and then also by all kinds of other musicians over the years). So, after choosing a classic like “Kind of Blue,” you could also have a universe of choices.

In fact, the whole CD remaster / reissue business has been predicated on one small bit of the possibilties in there being more than one version of classic albums.

(btw, the “Bitches Brew Sessions” reissue is, to me, often more enjoyable than the classic version.)

Post the LP-format, more of these possibilties seem more accessible, e.g., because physical packaging has ceased to be much, if any, constraint.
