I hope they are not printed in yellow text on orange background, as in one of the previous Miles box sets (don't remember which one)
That would be the In a Silent Way box.
As for the content of this box, there's this from www.miles-beyond.com:
"In addition, the liner notes for the boxed set are very sketchy and incomplete. For instance, there's hardly any track by track discussion, as was found on previous boxed sets. Instead there's the briefest of introductions by Bob Belden, an essay by Tom Terrell that's high on impressionistic word play but low on factual information on the music, and an entertaining and informatve essay by Paul Buckmaster, that captures the spirit of the early June 1972 sessions well, but obviously says nothing about the sessions that came afterwards, as he wasn't involved. There are also a few errors in the liner notes and discography."
