The original 1998 box set included metal binding and a slipcase cover.
The Complete Bitches Brew Sessions is a four-discbox set of music recordings by trumpeterMiles Davis. The set collects all tracks Davis recorded between August 19, 1969 and February 6, 1970, including the 1970 double albumBitches Brew in its entirety. However, the title of the box set is somewhat of a misnomer: outside of the Bitches Brew tracks themselves, none of the other tracks were recorded during the same August 1969 sessions that resulted in Bitches Brew. Furthermore, additional material recorded for, but not used in Bitches Brew (mainly rehearsal takes and unedited performances of the six album tracks), is not included in this set (though they later appeared on bootleg recordings titled Deep Brew Vol. 1 and Vol. 2).
When questioned by Paul Tingen why most of the material in fact was not recorded either for or at the same sessions as the original album, re-issue producer Bob Belden clarified how the team's thought process went. According to him and the engineer, all the songs Miles Davis recorded between August 1969 and early February 1970 used very similar line-ups to those on Bitches Brew, and the main thing they all had in common was the emphasis on keyboards. Every song in the set includes two to three keyboard players, most often Chick Corea, Joe Zawinul and Herbie Hancock. It wasn't until late February 1970 that Davis refined his concept by dropping the multiple electric pianists for a more guitar-heavy sound. Those following sessions were collected on The Complete Jack Johnson Sessions.
The Complete Bitches Brew Sessions is chronologically number "6" in a series of Miles Davis box sets issued by Columbia Records/Legacy Records/Sony Music (the numbering scheme refers to the chronological order of the original recordings, not the release order of the box sets themselves). The set was reissued on 11 May 2004 with new packaging.
