Matt Slocum, A Revolving Alliance Review

Matt Slocum | A Revolving Alliance Review: Three Voices, One Common Thread

By Nolan DeBuke

The most compelling jazz trios share an understanding that goes beyond knowing the changes, following the form, or agreeing on the tempo. There is a common musical thread, a point of rhythmic, harmonic, or structural agreement that allows each musician to develop independent ideas without losing the collective direction. On A Revolving Alliance, drummer and composer Matt Slocum, guitarist Emmanuel Michael, and bassist Larry Grenadier explore this relationship with remarkable sensitivity. Their music is built from layers of individual expression, those layers reveal an underlying conversation about where the music is going.

Released on Sunnyside Records, A Revolving Alliance presents seven Slocum compositions performed by a trio whose instrumentation provides considerable freedom. Without a pianist establishing continuous harmonic movement, Michael can shift between single-note lines, chords, electronic textures, and contrapuntal ideas. Grenadier moves between harmonic foundation, melodic commentary, and rhythmic development, while Slocum treats the drum kit as both a rhythmic instrument and a source of melodic color. Recorded live to two-track analog tape by engineer James Farber, the album preserves the immediacy of these interactions. The musicians’ decisions remain central to the listening experience.

The title track introduces the trio’s language through Slocum’s unaccompanied drums. Rather than establishing a conventional backbeat, he develops a melodic pattern from contrasting drum and cymbal registers. Low drum tones interact with sharper middle-register attacks and brighter metallic colors, creating a sequence of sounds that functions almost like a pitched melody. When Michael enters with a unison guitar figure, its articulation and tonal character extend the rhythmic language already established by the drums.

The common thread is an eighth-note pulse organized around shared phrase destinations. The musicians do not necessarily emphasize a predictable two-and-four pattern. Instead, their individual phrases converge on downbeat arrivals that give the music a clear sense of direction. This allows the rhythmic surface to remain flexible without becoming ambiguous.

Grenadier’s bass is essential to this relationship. His resonant tone and precise intonation provide harmonic definition, but his rhythmic placement also contributes to the ensemble’s developing conversation. As Michael moves into improvisation, the guitar lines unfold in clearly shaped phrases whose cadences remain connected to the bass and drums. Each musician contributes independent activity, yet the phrasing continues to acknowledge a shared rhythmic language.

Midway through the guitar solo, the trio converges on a unison rhythmic figure. The moment reveals the collective architecture beneath the improvisation. Michael subsequently expands into more active single-note lines, combining lyrical sustain with electronic delay, while Grenadier and Slocum develop complementary layers. The guitar’s effects are a part of the instrument’s expressive vocabulary, extending notes into overlapping textures that interact with the acoustic instruments.

Near the conclusion, Grenadier shifts into a two-feel, briefly opening the music into a more spacious, folk-jazz character. The change alters the atmosphere without disrupting the underlying structure. When the original groove returns, the ensemble reestablishes the rhythmic identity introduced by Slocum’s opening drum melody. The final cadence is decisive and collectively understood, yet it leaves the impression that the musicians have more to say. The composition ends because the ensemble agrees to conclude, not because its possibilities have been exhausted.

“A Disappearing Path” investigates the same musical principles through a different relationship between sound, harmony, and rhythmic displacement. Michael begins alone, using string rakes, electronic delay, and sustained textures to create overlapping layers. Repeated notes and electronically extended gestures form sheets of sound, making the interaction between instrumental technique and processing an essential part of the composition.

As the opening develops, the guitar establishes a rhythmic figure that brings bass and drums into the performance. Their entrance lands with purpose, immediately confirming a shared sense of time. From that point, syncopated motifs become the foundation for the composition’s development.

The musicians manipulate the placement of accents and phrases, creating changes in perceived metric emphasis while preserving an intelligible pulse. The effect is one of rhythmic expansion. A figure can move across the established time feel, suggesting a new direction without requiring the ensemble to abandon its original agreement.

Michael’s harmonic language introduces another level of uncertainty. His chordal movement incorporates shifting major and minor colors, complicating expectations about harmonic resolution. Extended phrases suspend anticipated cadences, while the bass and drums continue articulating the music’s rhythmic direction.

This creates an interesting distinction between harmonic movement and ensemble coherence. The harmonic destination may remain uncertain, but the musicians’ relationship to the phrase remains clear. Slocum and Grenadier do not simply accompany Michael’s explorations; they participate in shaping the space around them. Their responses allow the guitar to pursue more expansive ideas without disconnecting from the trio’s collective language.

The closing “A Dissolving Alliance” brings these principles into a more atmospheric setting. All three musicians enter together, establishing an ominous environment through low bass double-stops, guitar textures, and dynamic percussion. Grenadier’s woody resonance provides weight, while Michael’s electronically sustained guitar sounds move toward an almost synthesizer-like character. Slocum adds cymbal swells and carefully shaped drum gestures that contribute as much to the composition’s color as to its rhythmic movement.

The common musical thread is a subtle clearly articulated pulse. The musicians organize their interaction around the accumulation and release of musical energy.

Michael develops sustained intervallic gestures whose resonance and electronic processing create a kind of vertical melodic expression. Grenadier gradually expands from lower-register material into more prominent upper-register lines, while Slocum moves across the drum kit with increasing dynamic purpose. Each musician contributes to the ensemble’s growing intensity.

The first major climax emerges through a repeated, sustained guitar texture supported by the expanding activity of bass and drums. Rather than following this with a conventional harmonic resolution, the trio begins removing elements from the accumulated sound.

This gradual deconstruction is one of the album’s most revealing passages. As the instrumental layers separate, their individual identities become increasingly apparent. Grenadier introduces descending figures that suggest resolution without immediately providing it. Michael reduces his activity, and Slocum shapes the remaining space through controlled gestures and resonance.

Eventually, the musicians concentrate less on clearly articulated notes and more on the expressive qualities of sound itself. Swells, decays, and changes in register become the primary musical material. The final gestures reveal three distinct instrumental voices that remain connected even as their collective texture dissolves.

A Revolving Alliance’s sonic character contributes significantly to this achievement. Grenadier’s bass combines rhythmic authority with melodic flexibility. Slocum’s differentiated drum and cymbal tones allow percussion to participate in the ensemble’s melodic development. Michael’s guitar moves comfortably between acoustic clarity and electronic transformation, with delay and sustain functioning as extensions of his phrasing.

Farber’s recording gives these contrasting timbres room to register. The separation of guitar, bass, and drums makes it possible to follow the individual layers while appreciating their collective movement. The production serves the ensemble’s musical language rather than drawing attention away from it.

A Revolving Alliance particularly interesting in the number of ideas being presented. Slocum’s compositions establish recognizable musical relationships, but the performances gain their character from how the musicians interpret and develop those relationships as a conversation.

The rhythmic destinations, harmonic uncertainties, and textural transformations become opportunities for collective expression. Each musician understands when to reinforce an idea, when to challenge it, and when to leave room for another voice.

The alliance suggested by the album’s title is not a fixed arrangement of instrumental responsibilities. It is an evolving relationship built on listening, trust, and an unusually clear understanding of musical direction. On A Revolving Alliance, three independent voices demonstrate that the most convincing improvisational freedom comes from knowing precisely what connects them.
