That, my dear friend, would be the remastered version, with the "Feio" bonus track... ...Yeah, that's the headache one...
...Yeah, I found it, but, uhm, like I said, well... I had to uhh... Well... You know... -_- ...Yeah, I found it; I wish others could hear it too... Kuu...

EDIT: Ehh, here's a picture of what the Columbia Jazz Masterpieces edition looks like (it's distinct, no mistaking it); I've checked all "buy" links for it, but they all seem to lead to the remaster - ARGH:

EDIT 2: And furthermore, for the record; Jazz musicians aren't the only ones who are picky about their music... Now, I know he's done some Jazz stuff too, but, this guy's multi-genred; Bob Dylan is saying the same things about the new "remastered" versions of his albums, too; he doesn't like them the way they are now, and that they sounded better back then...
And, finally, everybody today that talks about Miles Davis and his time with Teo Macero, they all seem to think that Miles did what Teo wanted. Take "In a Silent Way," for example. Everybody seems to think - after hearing "The Complete In a Silent Way Sessions" - that Teo himself cut the fourty-eight reels of tapes, down to two, and played around a bit with what was left. Actually, the reverse is true; it was MILES who didn't want all that extra stuff on the record. There was so little left, that Teo had to take a piece from the beginning, and put it at the end - for both tracks! "Shhh/Peaceful/Shhh" and "In a Silent Way/It's About That Time/In a Silent Way." That's how Teo had to do it. And, one of the most important things, is that, these people think that Teo just mixed the tapes, and that was that. While it is true that Miles only came to the studio like, four times out of 29 years (The "In a Silent Way" thing was ONE of those times), Teo would always send Miles an acetate, or whatever, and he would say, "Do you like that Miles?" And Miles would either give his approval, or disapproval. Most people today, think that the opposite was true. Well, it certainly is TODAY, but, that's not how it was back THEN! If Miles didn't like it, they'd go back and do it again!
