MARK KIRSCHENMANN, Return to Sender

 What happens when a trumpet enters into conversation with a machine that refuses to behave? On Return to Sender, Ann Arbor-based composer, trumpeter, improviser and electronicist Mark Kirschenmann answers that question by turning a no-input mixer into something considerably more unpredictable than a piece of studio equipment. With its outputs patched back into its own inputs, the mixer generates self-oscillating tones, drones, pulses and bursts of feedback, becoming an electronic partner that Kirschenmann must hear, anticipate and answer in real time. The resulting eight-track, 40-minute album is a volatile meeting of experimental jazz, analog feedback, electronics and improvisation—but beneath its strange noises and alien textures is an unmistakable sense of musical play.

The concept is deceptively simple. Kirschenmann first captures an unedited, one-take improvisation on the no-input mixer, then responds with an unedited trumpet improvisation, later applying processing such as EQ, compression and reverb. Nothing is repeated or safely reconstructed in the studio. The machine generates the environment; the trumpet negotiates with it. Sometimes the instrument seems to lead, sometimes the electronics take over, and sometimes the distinction disappears altogether. It is less a trumpet accompanied by electronics than a conversation between two volatile personalities.

Kirschenmann has been exploring that territory for decades, electrifying the trumpet through pedals, plugins, MIDI and analog sound design. His work encompasses composition, improvisation and electronic experimentation, with performances and collaborations involving artists including Wadada Leo Smith, Myra Melford, William Hooker and Oliver Lake. On Return to Sender, that long fascination with the intersection of acoustic breath and electronic circuitry becomes particularly concentrated. The no-input mixer isn’t merely an effect. It is another performer.

The title track immediately establishes the rules—or perhaps the absence of them. A fast, shuffling

pattern of feedback and static creates a surprisingly persistent rhythmic foundation, punctuated by jarring, elevated tones that arrive like a bizarre form of Morse code. The repeated beeps and percussive blips gradually acquire their own hypnotic momentum. Then the trumpet enters way above them, wailing and bending through a trippy electronic haze before disappearing again, leaving the machinery to continue on its own. What might initially sound like malfunction begins to reveal an almost mischievous sense of structure: beneath the noise is a groove, beneath the groove is repetition, and within that repetitive cycle Kirschenmann keeps finding ways to disrupt expectations.

“Closed Circuits” makes the interaction even more playful. Scraping piercing tones ride a recurring shuffle while fizzy, cosmic pops and blips appear around the central framework. At times the sounds resemble some wonderfully warped interstellar adventure, with birdlike tones soaring and falling over a foundation that seems to scrape and rock back and forth. The repetition becomes hypnotic rather than merely abrasive, allowing the stranger sounds to function almost like melodic ornaments. Just when the recurring gesture seems settled, it drops away for a moment concentrated electronic mayhem before returning to the main motif.

“Circuit Breaker” brings the trumpet into particularly sharp focus. A foghorn-like vibrato establishes a low, rumbling presence while quick tones, scrapes and percussive strikes dance around it. Then Kirschenmann unleashes a distorted trumpet cry that sounds less like brass than a blistering electric-guitar solo. The transformation is startling, but it makes perfect sense within the album’s philosophy: the trumpet isn’t required to remain recognizable as a trumpet. It can become guitar, siren, electronic squeal or something with no conventional instrumental identity at all. As the piece develops, trumpet and machinery converge into a manic exchange, repeatedly stopping and restarting before exploding forward again.

“Touch Sensitive” moves into more spacious territory. An atonal burst of feedback gives way to a low, hypnotic drone while thin tones gradually intensify, recede and return. Buzzing sounds hover around the upper reaches of the sonic field, creating the sensation of electronic insects moving through an immense landscape. The most fascinating passages arrive when those swirling noises briefly take center stage before the drone reasserts itself. The effect is mesmerizing precisely because Kirschenmann resists the temptation to fill every available space. Silence and sustained tones become part of the composition.

From there, “Send to Returner” turns the dialogue into something resembling an extraterrestrial call-and-response. Lower percussive pulses answer needle sharp swirling tones; buzzing sounds accelerate while increasingly distorted blasts threaten to overwhelm the entire environment. The competing registers seem to communicate in increasingly urgent bursts, as if two alien systems are trying to establish contact. Eventually the intensity becomes so dense that the original foundations nearly disappear into distortion and electronic haze.

“Round Trip” introduces one of the album’s most kinetic rhythmic landscapes, a galloping low-end figure driving beneath strange, soaring trumpet modulations. The contrast is deliciously surreal: something earthy and almost physical keeps charging forward while weightless signals twist and weave overhead. The lower pulse eventually becomes hypnotic, with buzzing figures plucking around it like electronic insects as the trumpet reaches toward increasingly improbable heights.

“Haywired” is built around a wonderfully warped percussive vocabulary: rubbery scrapes, squeaks and pitter-patter figures that sound like an orchestra of overinflated balloons having an electronic nervous breakdown. Against that recurring motif, the trumpet begins to answer with its own distorted gestures, creating a back-and-forth between brass and circuitry. A siren-like cry eventually rises above the increasingly busy texture, sending the piece into a swirling exchange of squeals, pulses and sharply etched figures.

“Crosstalk” closes the album in a more mysterious register. A flexible high tone gives way to a stretched, vibrating low sound, followed by what resembles a record scratch launched into outer space. Trumpetlike calls rise and fall through the resulting vacuum, sometimes climbing toward the light, other times sinking back into darker frequencies. Then everything stops. For a few seconds, the silence itself seems to reset the piece before the strange dialogue begins again, now stripped of its supporting drone. The sensation if almost like following a laser dot across a dark wall – always moving, occasionally vanishing, then reappearing somewhere unexpected.

Return to Sender is challenging, but its rewards come from the same quality that makes its creation so fascinating: uncertainty. Kirschenmann never knows exactly what the no-input mixer will give him, and instead of fighting that instability, he turns it into the heart of the music. His trumpet listens, reacts, provokes and occasionally seems to surrender to the electronic current.

The result is a wonderfully eccentric album in which technology doesn’t erase human expression—it gives it something mercurial to push against. Across these eight one-take performances, Kirschenmann transforms feedback into rhythm, distortion into color and a mixing console into an improvising partner. Return to Sender may inhabit a strange musical universe, but it is one with its own logic, humor, tension and surprising beauty. Most importantly, it sounds like an artist genuinely discovering what might happen next—and inviting us to listen closely enough to find out.
