Not entirely related to the article, but I've noticed when I buy jazz box sets that include multiple discs of alternative takes or different live versions I find myself mostly listening to the original session. Bitches Brew is one of my favorites and I eagerly picked up the complete sessions set, but I keep coming back to the Japanese first pressing CD with the original mix. The box set is cool for the booklet, pictures and stuff, but I never listen to it.
I think a lot of booklets and inserts are simply fluff, but one of the things I absolutely love are the large glossy black and white photos taken by Francis Wolff during the Blue Note recording sessions inside the Music Matters vinyl. It's another experience staring at them and wondering what was going through those musicians minds at the time they created such amazing music.
