This is indeed a very beautiful object with reasonable price. Columbia / Sony made a real effort on the overall aesthetics. The 3 CD and DVD are shown in a box at the 33 t format. CD 1 contains the tracks from the original album as qu'issus the new mix directed by Mark Wilder in 1998 on the occasion of the release of the box "Complete Bitches Brew Sessions". The 2nd CD contains the alternate were already known and an unpublished Spanish Key plus versions 45 t of different titles, which are at least as curiosities. The third CD features a concert of August 1970 of good quality (the sound is good) without being overwhelming. The DVD offers for its part a concert filmed en couleurs by Danish television in November 1969, there again globally of good invoice. The cabinet still contains the reproduction of the original album in double vinyl audiophile 180 g, this time such stands following the realized mixing by Téo Macero at the time, so that I do not find that it be surplusage, further that the object itself is beautiful. As shown in the accompanying booklet, lovely though without great contribution in terms of substance, it seems that as the version mixed in 1998 (1st CD) as the original (1970) have undergone a remastering by the Mark Wilder care. Finally, collector oblige, found a wallet containing "memorabilia" fun that have already been the subject of a description in the previous comment. In summary, a very timely purchase for fans of Miles, there's really no misrepresentation of the product.
