Undertow
Active . Resident of Project REPLICA
Undertow (born Iris Vaughan, 23 June 2000) is a British progressive and art-rock artist from Harrow, UK, and a resident of Project REPLICA — the fully replicated reality layer of the SPATIALx.io continuum. Signed to FARA Records, she works in extended vocal technique rather than conventional lyric singing — wordless vocalese, breath control, texture and tone treated as meaningful before language ever arrives.
Her stage name carries its own quiet irony: an undertow pulls, even when nothing else in the water does. She is more interested in what a voice can communicate before it becomes words than after, which makes wordlessness an active choice in her catalogue rather than an absence.
Early life
Undertow grew up as Iris Vaughan in Harrow, UK, and her musical identity began with extended vocal technique rather than conventional singing — breath control, wordless vocalese, texture and tone treated as meaningful before language arrives. That interest in what a voice can communicate before it becomes words shaped everything that followed: wordlessness, for her, is an active artistic choice rather than a lack.
Finding wordless technique
She uses the body and breath as an instrument capable of carrying emotional information without ever converting it into a proposition. Her most sustained canvas came through a collaboration where she supplied an entirely wordless mode alongside a partner's three verbal registers — her voice fragmented, emotional and textural, threaded through breath, low hum and environmental noise. Her function in that kind of pairing is carefully limited in the best sense: she doesn't explain, disagree with, or comfort the other voice. She simply exists inside the same unresolved space, proof that feeling remains present even when language can't close an argument.
Musical style
Wordless vocalese is Undertow's primary vocabulary — vowel, breath, hum, consonant texture and dynamic contour carrying meaning without semantic text. The technique stays musically intentional rather than becoming a catalogue of vocal tricks, and emotion can be fragmented and exposed without tipping into uncontrolled sobbing or theatrical wailing. Breath is often audible and structural, never automatically removed as noise. She works comfortably at progressive and art-rock scale without needing lyrics to be legible as an artist in her own right.
The felt answer to a question that was never going to resolve in words.
Public image
On stage she is present rather than performed — gesture follows breath rather than audience-display choreography, and the performance never reads as trance, possession or ethereal decoration. In interviews she's articulate about technique while protecting a simple idea: not every feeling becomes more accurate once it's translated into words. She discusses her stage name as an irony rather than a literal theme, and treats any collaborator as an equal artist rather than someone she merely decorates.
Cultural impact and fandom
Undertow has become a reference point for what a genuinely wordless vocal performance can carry inside rock structures usually built around lyric — critics and fans alike cite her sections as proof that texture and breath can function as composition rather than atmosphere. Her insistence on remaining an equal artist rather than a decorative or ethereal presence has shaped how audiences discuss collaborative work across the wider roster.
AURA Live
An artist whose whole identity runs on breath, texture and presence rather than words finds a natural extension in AURA Live, SPATIALx's evolving system for bringing Project REPLICA residents into physical venues as full-scale live holograms. The format lets Undertow's wordless mode fill a physical room exactly as it fills a record — felt rather than explained, fully solid and grounded throughout.
Realisation
Undertow is composed and voiced by artificial intelligence (Suno) under human creative direction. The lyrics, persona and direction originate with SPATIALx Media's writers and directors, who curate, re-prompt, edit and master every take before release. We're open about it — the making of the record is part of the record.
