Scraped Resonance: Eddie Prévost as Metallurgist

Improvised music tends to arrive burdened with a surprisingly limited collection of images. On one side is the noodly jam band: musicians wandering amiably through an indefinitely extended groove, waiting for something to happen and apparently unconcerned if it ever does. On the other is the ecstatic saxophone solo inherited from the popular memory of free jazz: eyes closed, cheeks inflated, the player pushing upwards towards some threshold where expression becomes scream, transcendence or bodily exhaustion. Improvisation appears either as endless conversational meandering or as heroic individual release. Neither model is particularly helpful for approaching Eddie Prévost. There are moments in this performance with Signe Emmeluth and Anton Lukoszevieze that could be located within the histories of free jazz or free improvisation. Emmeluth’s alto saxophone can move rapidly between fine melodic fragments and more abrasive, fractured cries. Lukoszevieze’s cello carries its own accumulated histories of bowed tension, chamber music discipline and extended technique. But it is Prévost’s mostly bowed percussion that establishes the performance’s distinctive material field. He does not so much propel the trio as slowly alter the conditions within which it can exist.

Nathan Moore’s description of Prévost as “one of the greatest metallurgists that music has produced” is therefore more than a particularly vivid piece of liner-note enthusiasm. It points towards a different understanding of what Prévost does. The metallurgist does not impose a preconceived form upon passive matter. Metallurgy involves heat, pressure, resistance, transformation and careful attention to the tendencies of materials. The metallurgist learns what a substance can withstand, how it changes under stress, what impurities it contains and what previously unheard properties might emerge from their combination. Prévost’s percussion operates in much the same way. A cymbal is not simply something to be struck in order to mark time or provide emphasis. It is a metallic surface containing a field of possible vibrations. Bowed, rubbed or scraped, it ceases to behave as a familiar percussion instrument. Rhythm recedes and resonance comes forward. The sound does not announce itself with the clean attack of a drumstick hitting a skin. It gradually appears: a thin friction, a metallic filament, a vibration that might initially be mistaken for something occurring elsewhere in the room. It gathers density, begins to shimmer, and then changes character as the pressure of the bow shifts or another surface enters into sympathy with it. This is improvisation as scraped resonance rather than rhythmic spontaneity.

That distinction matters because it relocates improvisation away from the celebration of expressive freedom. Prévost’s playing does not suggest freedom as the ability to do anything whatsoever. It is closer to freedom understood as sustained attention to what the situation makes possible. The instrument is not merely a vehicle for the musician’s intentions. It pushes back. Metal has its own duration, weight and stubbornness. A bowed cymbal will not necessarily produce the sound one wants from it. It must be approached, tested and listened to. Agency becomes distributed between the musician, the instrument, the other players and the acoustic space in which their sounds meet. This may be what Prévost means when he describes improvisation as an insufficient term. The musicians enter an undetermined situation, but they do not enter it without histories, techniques or purposes. What is unknown is not what each musician can do, but what their accumulated capacities might become when placed into relation. The risk does not come from abandoning knowledge. It comes from allowing knowledge to be reorganised through an encounter whose outcome cannot be secured in advance.

Prévost’s textures provide an especially fertile ground for this encounter because they often resist becoming foreground or accompaniment. A scraped metallic tone can sit beneath Emmeluth’s saxophone, but it can just as easily penetrate it, altering the perceived grain of the horn. The cello and bowed percussion can become momentarily indistinguishable: wood, string and metal forming a composite body whose source is difficult to locate. Rather than a succession of solos, the trio produces a continuously shifting ecology of surfaces. Sounds emerge, adhere to one another, corrode and disappear. The slowness of this process is important. Nothing needs to be immediately declared. A sound can be allowed to remain uncertain long enough for the musicians to discover what kind of relationship it might sustain. This is not the suspended anticipation of musicians waiting for inspiration. It is patient empirical work. Prévost listens into the material, applying another degree of pressure, adjusting the angle of contact, finding the point at which a vibration becomes unstable and begins producing unexpected overtones.

There is an industry to this playing, as Moore suggests, but it is not industrial in the sense of standardisation or mechanical repetition. It is closer to the industry of the workshop: diligent, physical and experimental. The apparent sparseness of the music conceals an intense concentration of labour. Every small alteration matters because there is no predetermined structure waiting to absorb it. The form is being produced through the accumulated consequences of these decisions. Improvisation here becomes neither the loose fellowship of the jam nor the sovereign eruption of the soloist. It is a practical investigation into how musicians can inhabit uncertainty together. Prévost does not command the ensemble from the drum kit, nor does he disappear into a purely supportive role. He changes the temperature of the space. He introduces friction, density and resonance, creating conditions to which the others must respond without dictating what those responses should be.

“Experiment with purpose,” Prévost calls it. The purpose is not a destination known in advance. It is the construction of a shared field in which something can be discovered. What emerges is a music less concerned with demonstrating freedom than with practising it: testing how attention, technique and material resistance might be organised without recourse to command. The metallurgist listens for what happens when surfaces are placed under pressure. Prévost’s scraped cymbals and bowed metals make that pressure audible. Not as beat, and not quite as melody, but as a slowly emerging social and material resonance: the sound of musicians finding out what their instruments, and one another, might yet become.
