Miles Davis — Bitches Brew

The album's opening and longest sustained argument for the new format. Macero constructs the first minute from looped fragments, a stop-start stutter that finally releases into the full ensemble. Once the band enters, the piece moves through shifting densities: passages where the three electric pianos layer chords in different rhythms, stretches where the drums drop to near-silence and let the bassists and percussion carry the pulse, and a long central section where Davis and Shorter trade lines over a modal vamp that barely moves harmonically. The editing is most audible here—micro-loops of one-second fragments repeated five times between 8:54 and 8:59, and several longer tape loops that create false climaxes. The track earns its twenty minutes through the contrast between the constructed opening and the loose, collective improvisation that follows, though the middle section drifts longer than it needs to. Maupin's bass clarinet adds a lower-register voice that thickens the ensemble sound without crowding the trumpet and soprano. This is the clearest demonstration of what the album is trying to do: turn the rhythm section into an environment rather than a foundation, and use the studio to build structures the band could not have played live.

The title track is the album's longest piece at twenty-seven minutes, and the most patient. It opens with sparse electric piano chords and a quiet, rubato statement from Davis before the rhythm section gradually assembles around him. The harmonic movement is glacial—long stretches on a single modal center with the pianos shifting voicings rather than changing chords—and the soloists work in short, fragmented phrases rather than extended lines. Shorter's soprano enters around the ten-minute mark, and his interplay with Davis becomes the track's focus: two voices circling each other over a rhythm section that is more textural than propulsive. Macero's fifteen edits include several five-second tape loops that repeat certain figures, creating a sense of stasis even as the players move forward. The track's length is both a strength and a weakness. It allows the music to develop without rushing, and the slow build to the final section where the full ensemble locks into a denser groove is effective. But there are several minutes in the middle where the rhythm section embellishes without adding new information, and the listener is left to decide whether the openness is generative or merely patient. For those who stay with it, the payoff is in the final five minutes, where Davis's most aggressive playing on the track cuts through the wash with lines that finally insist rather than suggest.

The strongest track on the album in terms of rhythmic clarity. Spanish Key builds on a repeated bass figure that gives the massed rhythm section something to lock onto, and the result is the closest the album comes to a groove that could sustain a live performance without editing. The three drummers and two percussionists layer patterns that suggest both Latin rhythms and funk, but without settling into either, and the two bassists play in near-unison for much of the track, reinforcing the central figure. Davis's solo is more melodic here than elsewhere on the album, with phrases that are rhythmically tight and responsive to the pulse. Shorter's soprano solo in the second half is equally strong, and the interplay between the two horns and the rhythm section feels like a conversation rather than parallel improvisations over a static backdrop. Maupin's bass clarinet is present but less prominent than on Pharaoh's Dance. At seventeen and a half minutes, the track is still long, but it justifies the length by varying the density and giving the soloists room to develop ideas without losing the thread. This is the track that shows the format working: the massed rhythm section creating a complex, shifting foundation that still has enough shape to push the improvisers forward. If the rest of the album had this level of internal momentum, the length would be less of an issue.

A brief guitar-and-rhythm interlude on which Davis does not play. McLaughlin's electric guitar is layered over sparse accompaniment from the pianos, bass and light percussion, and the piece functions as a textural break rather than a developed composition. It is pleasant, but it does not advance the album's argument or provide a necessary contrast to what comes before and after. At four and a half minutes, it is the shortest track, and it feels like a studio sketch that could have been left off without loss.

The only track presented exactly as recorded, with no editing or studio effects. It is also the most conventional piece on the album: a funk vamp with a clear groove, anchored by a repeated bass figure and a steady backbeat from the drums. The rhythm section is still large, but here the players lock into a single pulse rather than layering polyrhythms, and the result is more propulsive than anything else on the record. Davis's closing solo is the most aggressive performance on the album, with fast runs and repeated ventures into the trumpet's upper register. The tone is raw, the phrasing fragmented, and the lines snarl rather than float. It is a reminder that Davis's electric period was not only about ambient textures and slow harmonic movement; it also incorporated the energy and directness of funk. At fourteen minutes, the track is long enough to develop the groove and give the soloists room to work, but it does not overstay. This and Spanish Key are the two tracks where the massed rhythm section feels like it is driving the music rather than simply providing a wash for the soloists to float over.

A subdued modal meditation that closes the album on a quiet note. The rhythm section is sparse, the harmonic movement minimal, and Davis's trumpet is muted and contemplative. Shorter's soprano is present but restrained. The track is well-played, but it does not provide the sense of resolution or climax that a closer of this length might offer, and its placement after Miles Runs the Voodoo Down—which already serves as a release of tension—makes it feel redundant. At nearly eleven minutes, it is longer than it needs to be, and the final minutes coast on texture without building toward anything. It is the weakest track on the album in terms of function, though not in terms of performance.
