I would give this expanded edition of "Bitches Brew" five stars just for the remastering. This amazing album now has the rich, full sound the material always deserved. The bottom end in particular, really comes alive, making "The Complete Bitches Brew" a totally immersive experience.The title is somewhat misleading, as none of the additional material was actually recorded at the same August 1969 sessions as "Bitches Brew," but at separate sessions a few months later. However, most of the same musicians are used, and the additional pieces are fascinating and really great on their own terms. Some of these tracks have been released on previous Miles Davis albums, but some have not. At any rate, it's nice having all this great music in one place.Finally, the packaging is a model of how this sort of thing should be done: a solid, practically unbreakable outer shell housing a heavy-duty cardboard holder of all 4 discs. Best of all is a booklet containing lengthy observations on the album, Ralph Gleason't original liner notes, and detailed descriptions of how this album was made. That last part is essential reading for true fans, because "Bitches Brew" was as much the result of clever manipulation of tape loops, echo and other studio effects by producer Teo Macero as it was of the magnificent playing of this all-star cast of musical geniuses. An annotation of just the first few minutes of "Pharoah's Dance" is fascinating reading in its own right.If you like Miles Davis, if, like me, "Bitches Brew" is on your list of desert island albums, then this is the ultimate version of it. My highest recommendation.
