The Chronicle of an Era: The London Underground Networks, the Post-Punk Collision, and the 1981 Affinity Pressings
By the arrival of 1981, the landscape of British experimental art was operating under a heavy, highly polarized socio-political cloud. The aggressive rise of Thatcherism, industrial decay, and intense urban unemployment had fueled a bleak, confrontational counter-culture across the United Kingdom. In the musical underground, this friction sparked a brilliant, historic convergence: the structural iconoclasm of the London free-improvisation vanguard began to bleed directly into the jagged, DIY anti-authoritarian energy of the post-punk and industrial noise movements. No longer confined to polite avant-garde galleries, creative improvised music was being performed in damp basement clubs and squatted warehouses, weaponized as a raw, physical refusal of societal standardization.
It was within this intense climate of collective resistance that master drummer, conceptualist, and community organizer John Stevens assembled his massive, shape-shifting Spontaneous Music Orchestra (SMO) to document their historic live configurations. Released on the highly respected Affinity Records—a label dedicated to archiving both American free-jazz giants and homegrown radical experimenters—the album In Concert was captured with a gritty, hyper-realistic, and uncompromisingly dry live documentary mixing style.
The engineers bypassed any attempt to smooth out the collective’s rough edges with artificial salon echo. Instead, they allowed the dense, chaotic multi-instrumental bleed, the physical scrapes of folding chairs, and the high-tension room air of London’s live spaces to dominate the master tape, delivering a permanent blueprint for Egalitarian Large-Ensemble Improvisation.
The Biography & The Concept of the Masterwork: John Stevens and the Architecture of the SME/SMO Search
John Stevens (1940–1994) stands as one of the most foundational, intellectually rigorous, and fiercely original architects of European free improvisation. As a co-founder of the seminal Spontaneous Music Ensemble (SME) in 1966 alongside saxophonist Trevor Watts, Stevens spent decades systematically dismantling the conventions of traditional jazz timekeeping and harmonic hierarchy. Influenced equally by Anton Webern’s spatial compression, Albert Ayler’s spiritual cry, and the organic micro-rhythms of nature, Stevens developed a revolutionary pedagogical system known as “Search and Reflect.” This method was designed to allow anyone, regardless of academic training, to engage in total, non-hierarchical sonic dialogue.
The absolute masterstroke of In Concert lay in the scaling up of this micro-improvisational philosophy to the proportions of a full orchestra. Stevens expanded the intimate, conversational ethics of his small groups into a massive, democratic swarm of collective consciousness. The orchestra featured a multi-generational battalion of British avant-garde titans, including long-time brothers-in-arms like saxophonist Evan Parker and trombonist Paul Rutherford, alongside radical players from the younger noise and free-jazz networks.
Stevens completely rejected the role of the traditional autocratic conductor or composer. He did not provide written scores or chord charts. Instead, he steered the SMO using a series of real-time vocal cues, physical breathing prompts, and minimalist conceptual rules (such as “if you cannot hear your neighbor, you are playing too loud”). The orchestra functioned as a fluid, self-correcting ecosystem where no single voice dominated the stereo field, transforming the music into an unyielding, panoramic wall of acoustic democracy.

The Anatomy of the Vinyl: A Sensorial Excursion Through Microtonal Hisses, Bowed Resonances, and Sudden Sonic Eruptions
To drop a high-grade stylus into the dense, micro-grooved vinyl of an original 1981 Affinity pressing of In Concert is to invite a storm of pure, unvarnished acoustic texture directly into your listening room. The soundstage is remarkably wide, deep, and chaotic, mapping the large physical horseshoe configuration of the orchestra with absolute geometric transparency. Side A is entirely consumed by the staggering, continuous epic “In Concert Part 1”. The performance materializes out of absolute human silence with Stevens’ signature, ultra-minimalist percussion work: a series of dry, high-pitched rim-clicks and rapid, micro-textural snare scratches executed with small wooden sticks.
Suddenly, the collective swarm begins to wake up. The acoustic imaging captures a remarkable, microscopic universe of friction: the high-register, insect-like pizzicato chirps of acoustic double basses being scraped below the bridge, the breathy, key-clicking sighs of unblown woodwinds, and the metallic, sliding groans of muted trombones.
Evan Parker’s soprano saxophone enters the left speaker like an absolute swarm of hornets, utilizing continuous circular breathing and split-reed harmonics to create a rapid-fire, microtonal texture that sounds more electronic than organic. Rather than building toward a traditional, heavy-handed jazz crescendo, the orchestra operates via a series of sudden, highly volatile dynamic shifts—collapsing down to a single, fragile thread of cello static before instantly exploding into a thundering, multi-voiced roaring cloud of acoustic sound waves that pushes the room’s physical air boundaries.
Flip the heavy vintage wax over to Side B for the devastatingly intense, hyper-focused dialogue of “In Concert Part 2”. This movement is an absolute masterclass in spatial tension, vocalized instrumentation, and the collective control of noise. The piece opens within a deeply eerie, minimal acoustic void where the brass section executes a series of long, microtonal breath drones that mimic the sound of industrial wind tunnels or ocean depths.
Stevens guides the group from his drum kit not by enforcing a steady rhythm, but by injecting sharp, pointillistic cymbal splashes that drop like iron bolts into the stereo field. The collective dialogue reaches an absolute state of ego-less telepathy; the boundaries between individual instruments completely dissolve into a singular, breathing texture—a massive, undulating sound sculpture that burns with an intense, quiet flame before abruptly decaying into the raw, ambient room air and the rhythmic, hypnotic crackle of the vinyl run-out groove.
The Legacy and Modern Coordinates: The Holy Grail of British Avant-Garde Collectivism
The historical, critical, and cultural trajectory of In Concert stands today as one of the most vital, aggressively studied, and intellectually revered milestones in the narrative of independent recorded art. For decades, original copies on the Affinity imprint remained highly sought-after artifacts among global vinyl archivists, celebrated not just for their scarcity, but for their complete, uncompromised refusal of commercial structure. It stood as definitive historical proof that a large ensemble could achieve total, unrestricted freedom without collapsing into directionless chaos, proving the structural durability of Stevens’ radical egalitarian philosophies.
Today, the modern coordinates of Jazz Latitude look directly back to this 1981 London document as an essential, foundational textbook for the contemporary international creative underground. The twenty-first-century global avant-garde—championed by large improvising collectives across London, Berlin, and Tokyo who merge DIY noise aesthetics, modern composition, and radical anarchist organizing models—reads In Concert as a sacred, visionary blueprint. It remains permanent proof that when master musicians strip away hierarchical charts and commercial boundaries, they engineer a language that is structurally timeless, deeply democratic, and boundlessly free. John Stevens and his radical British orchestra carved a permanent, brilliantly glowing slate-and-iron coordinate on our map: an immortal European outpost that stands as an eternal monument to the triumph of the collective human soul.
