ICMC 2025

The Soundwalks track of ICMC 2025 received 31 submissions from sound artists and composers across five countries, marking an exciting expansion of the conference into site-specific, locative audio experiences. ICMC 2025 partnered with the Echoes platform to enable participants to create immersive soundwalks in Boston's historic Public Garden and Common, transforming these iconic green spaces into canvases for sonic storytelling.

We accepted 18 soundwalks that exemplify the spirit of "Curiosity, Play, Innovation" by reimagining how audiences experience computer music beyond traditional venues. These works invite listeners to become active participants, exploring layered histories, hidden narratives, and ecological soundscapes through GPS-triggered audio that responds to their physical movement through space.

The selected soundwalks demonstrate remarkable creativity in their engagement with place. Some artists excavate forgotten histories and commemorate untold stories, while others create playful interactions between the virtual and physical environment, turning a simple walk into a journey of sonic discovery. Artists, both local and international, rose to the unique challenges of composing for outdoor spaces where birdsong, wind, and urban life become part of the compositional palette.

We thank the 18 reviewers who evaluated these pioneering works, considering not only their artistic vision but also their innovative use of mobile technology and sensitivity to site-specific contexts.

Available throughout the conference via smartphone, these soundwalks invite us to reconsider the very boundaries of the concert hall and explore computer music as an embodied, ambulatory art form.


Walks

Nature Walk

Nature Walk

**Nature Walk** is set in Boston Common and Public Garden. Enter or dwell at any point. It is in three sections: The **Great Elm Remembers** surrounds **The Great Elm** in Boston Common and is a meditation on deep memory — both public and private. The Great Elm is no longer standing, yet it endures in our public memory. And for many — those still living and those now passed — it holds personal memories, some of which are woven with its public history. These memories have a power to connect us across time — to a moment, a people, or perhaps a person. In cultures native to this place, the songs of birds are sometimes heard as messages from the spirit world. It seemed fitting to place virtual flocks on this now phantom tree. Inhabiting its absence are sonic populations of local birds. At the tree’s core, these birds resonate wind chime bells to aid their messaging. These in turn resonate down through its roots — and its still- remembering rhizosphere. **Gibbons in The Garden** presents a tropical forest surrounding the Boston Public Garden Lagoon. There is a tradition at the Garden of planting tropical flora in the summer months. This stems from a Victorian era fascination with the Tropics. We extend that here with recordings of a 130 million year-old forest - among the oldest on earth - that I made in Sabah, Malaysia (Borneo) in the Fall of 2024. Several recordings are set around the Lagoon. A small group of gibbons have broken free to sing throughout the Garden along with a few of their Sumatran cousins. Near the entrance on Charles St, one of the forest soundscapes is mixed with tones derived from a mRNA sequence that is the focus of the next section. Running between the above two biomes between Charles Street and The Great Elm is **Ribosome Retune**. The name is a play on the focus of this section - exploring Just Intonation on scaffolding of gene expression. This section of the walk dives into a smaller scale of nature, but in a way with significance for Boston. Musically, I was interested in spatial animation of harmonic tunings mirroring natural patterns and processes. I was drawn to Just Intonation (JI) for its clarity and richness of harmony that defies Western tuning’s (12-Tone Equal Temperament) 12-TET categorizations of consonance and dissonance. This unmooring from 12-TET categorical intervals is abundant in the finer details of intervalic combinations and their relation to functional harmony. This more nuanced psychological space is what I wanted to explore. But it’s a vast and chimeric domain. So I sought a natural architecture on which to structure this exploration. I chose gene expression for a couple of reasons. Our recent experience with the Covid-19 pandemic brought broad public awareness (and gratitude!) to the field of biochemistry in its rapid development of mRNA vaccines. Secondly, for this ICMC, it seemed a modest way to honor the enormous contributions to this field from across Boston’s great research institutions. Indeed, last year (2024), Victor Ambros at Massachusetts General Hospital and Gary Ruvkun at Harvard Medical School were awarded the Nobel Prize in Physiology or Medicine for their work on microRNA regulation of mRNA. But what is that? Might it offer a “natural scaffolding” on which to explore JI? This piece is that exploration - a personal adventure to learn about the fundamentals of gene expression voiced through spatial JI. It is an exploration, not an explication. That is, I wouldn’t claim today’s result is a salient “sonification” of RNA transcription and translation. But I’ve tried to represent the biochemical qualities and processes coherently, and - as for any musical work - hopefully in ways that offer worthy listening. This section uses the coded section of the LIN-14 gene (that used in Ambros and Ruvkun's work) to generate tones from its bases and spin out chords of their coded amino acids using the amino acids' molecular weight, polarity, and charge to affect their chords' tones, size, spread, and rotation. The short LIN4 miRNA sequence enters above the walk and moderately stifles amino acid chords in its proximity. More information on the mRNA to Just Intonation mappings is found in their zones: "Ribosome Retune - LIN-14 Coding Region (CDR) Nucleotides and Amino Acids" and "Ribosome Retune - LIN-14 5' Untranslated Region (HTR)". The cover image is from ***Nature Walk***, by Teresa Parod. This painting is one of Teresa's garage door murals in Evanston, IL, USA.

jaden piblik

jaden piblik

A collaboration with between Cantabridgian poet Jacques Fleury and Bostonian musician Rachel Devorah Wood Rome. A diverse collection of plants from around the world live together in the Boston Public Garden, embodying the ideals and contradictions of the United States. Heralded as the "first public botanical garden in the United States," this historic site reflects a uniquely American paradox: the aspiration for multicultural democratic inclusivity juxtaposed with the tenants of colonialism. Nature is not left to thrive on its own terms but meticulously curated, shaped to conform to Victorian notions of beauty and order. jaden piblik is an electroacoustic soundwalk setting of Jacques Fleury's Haitian-Creole translation of the English-language poem "Treeness" by Jason Allen-Paisant. The work bridges languages and traditions, resonating with the complex, layered histories embodied in the Public Garden itself. Rachel Devorah Wood Rome is an improvising electronic musician, educator, and labor organizer who machines for their patience and capacity to remember. She is employed as an Assistant Professor of Creative Coding at Berklee College of Music and as Vice President of Full-Time Faculty for MS1140 AFT Massachusetts. https://racheldevorah.studio/ Jacques Stanley Fleury is a Haitian-American Poet, Educator and author of four books. He has a degree in Liberal Arts and is pursuing graduate studies in the literary arts through Harvard University. His first book Sparks in the Dark: A Lighter Shade of Blue, A Poetic Memoir about life in Haiti and America was endorsed by the Boston Globe. Fleury is prominently featured in newspapers, anthologies, libraries and literary journals worldwide.Visit him at: http://www.authorsden.com/jacquesfleury

Ephemerospherical walk: Bats of the Public Garden

Ephemerospherical walk: Bats of the Public Garden

This roughly 1/3-mile sound walk should last around 15 minutes, but can be longer as desired, and listeners may pause at any point of the walk, as all sound events are looped (except the last one). Listeners will start at the Ether Monument, following a path from there east towards the pond and then south along its bank. Listeners are invited to take this path as slowly as they like. The action picks up a bit on the bridge over the lagoon, then walk east to finish the walk at the Bagheera Fountain. Bat walking is by necessity an active form of listening: When I’ve participated in bat walks, using my bat detector to make the animals’ calls audible, the other participants - often including young children - looked up in wonder whenever they heard a call, knowing a bat was about to flit by and would only be visible for a few moments. Bats don’t creep into, or come crashing into, your auditory attention. This sound walk is designed to suggest the feeling of a bat survey on foot. Normally a nighttime activity done with ultrasonic detectors, Bats of the Public Garden can be experienced any time of day. Rather than an attempting to be “realistic,” the soundscape is layered, shifted, and processed to communicate the urgency, mystery, and musical rhythm that arises from the joint improvisation of animal and human rhythms. At various points, the sounds of the bats will be combined with sounds from other ephemeral occupants of the garden - frogs, crepuscular birds, amphibians, and fish - along with voices of mythical, imagined, and other-than-nonhuman beings.

Curated Cacophony: Exploring AI's Sonic Footprint

**_To experience this soundwalk as intended, please begin at the AMC Boston Common 19 movie theater and follow the suggested walking path highlighted in the map._** Join me for an immersive audio journey through the heart of Boston, starting at the AMC theatre and weaving through the Boston Common. This soundwalk is my exploration of the evolving relationship between humanity, art, and artificial intelligence. As you walk, you'll be guided by my voice and that of my AI counterpart, prompting you to consider the world around you in a new light. Each stop on the path raises new questions about authenticity, creation, and what it truly means to be human in an age of rapid technological change. The Path: To hear the full narrative for each stop, **please pause your walk when you hear the narration begin**. Once the audio for that stop has concluded, you can continue on to the next location. The journey will take you to the following places in order: - AMC Boston Common 19 - Boylston Station (at the park entrance) - The Parkman Bandstand - Soldiers and Sailors Monument - Frog Pond - Brewer Fountain - Park Street Church This walk is an invitation for you to listen, to look closer, and to ask your own questions. Let's begin, and thank you 🧡

An Invitation to Play

An Invitation to Play

Instructions: Enter the Garden through the gate at Arlington and Commonwealth Ave. Proceed to the space right between the two fountains in front of the George Washington statue and begin. (Tip: the instructions will guide you around the Garden, but if you are ever at a loss on what to do next... just follow the line) Description: As children we often look at the world through the lens of play - sidewalk cracks invite us to avoid stepping on them under perilous threat; trees for climbing stand out amongst the rest; we determine which house hides the terrifying monster and walk on the other side of the street. However, as we reach adulthood, we often lose this lens of play. This soundwalk invites listeners to adopt a playful attitude toward their natural spaces and the people around them. For fifteen minutes, as listeners stroll around the lake in the Boston Public Garden, we will create the space for a playful interaction with the world. Together, we will explore the positive psychological benefits of play and how a playful attitude affects us and colors our lived experiences. We will hear stories of designers who seek to create playful moments in daily life - designers such as Bernard DeKoven who spent his life inviting others to participate in what he called “the infinite playground.” Finally, by exploring some of the aesthetic elements of play (including imagination, playful objects, flow, and the magic circle), we will create opportunities for playful attitudes towards nature, others, and ourselves.

Common Quantization Noise

Common Quantization Noise

Common Quantization Noise revisits Vox Pop and environmental recordings made in the Boston Common and Public Garden and re-contextualizes them 15 years later. It functions like a time capsule where we can hear voices documented over a decade ago and consider how their testimonies resonate with our experiences with urban nature today. Depending on the walker's location on this path, they can adjust their position towards a cleaner recording, versus one that is contaminated by digital noise. Following the designated route as a repeated path, would be optimal to experience multiple variations over time. As movement and listening duration recur cyclically they provide time for reflection on the experience and ideas being presented. The walker can make decisions about the course to follow and whether to move towards hope in nature’s resilience after being contaminated, or be subsumed in its destruction.

Awake and lift their heads in all their prismatic glories

Awake and lift their heads in all their prismatic glories

MATTHEW AZEVEDO, University of Massachusetts, Lowell USA INGA CHINILINA, Brown University, Providence USA "Awake and lift their heads in all their prismatic glories" merges the invisible worlds of electromagnetic fields and seismic vibration with the auditory environment of the Boston Public Garden and composed score to create an immersive sound experience structured by the listener’s unique path through the work, evoking the yearly blossoming and renewal of the garden. The contours and title of the piece have been drawn from Charles W. Stevens’ article "The Boston Public Garden," published in the 1901 edition of New England Magazine, which provides the reader with a tour of the garden and history of the transformation of the “waste land” left when fire destroyed a series of rope walks into “a public exhibition of horticultural beauty such as can be seen in perhaps no other city of the Union.” Additional Performers: John Popham, Cello T.J.

Whisper in a Lily's Ear

Whisper in a Lily's Ear

A data sonification piece based on five poems written by female poets who lived/worked in Boston over the course of its history: Phillis Wheatley (1753-1784), Ellen Sturgis Hooper (1812-1848), Elizabeth Stuart Phelps Ward (1844-1911), Gertrude Hall (1863-1961), and Jadene Felina Stevens (1947-2013). Each poem is tied to a prominent monument or landmark within the Public Garden, over a walking path covering approximately a half-mile from its southeastern to the northwestern points. In addition to recorded readings of the poems, two selections of modern-day sound recordings made in Boston accompany each poem, with varying pitches determined by word and letter frequency data within each poet's body of work, and within the overall English language. Surrounding the monuments/poems, ambient music from each relevant time period plays in the background. 18th Century:"Sodgers Return", by Sturbridge Colonial Militia; Early-19th Century:"Home, Sweet Home (Folk-Song)" by Martin R. Lucas (Producer); Mid-19th Century: "Alexander's Ragtime Band" by Miff Mole And His Little Molars; Late-19th Century: "In a Blue Summer Garden" by Duke Ellington, Billy Strayhorn, & Joe Shulman; 20th Century: "Crystalline Neurons" by PrimalHouseMusic.

Ryan Ingebritsen: A Walk Into the Past: The Soundscape of Pre-Colonial Shawmut Peninsula (Ambisonic Version)

For this hike, only choose 3D if you have head tracking headphones such as Apple Airpods with spatial audio. Otherwise, Choose 2D. A Walk Into the Past transports the listener back in time through sound within the boundaries of modern day Boston Common. Within this historic site, listeners can hear a sonic emulation of the sound environment that would have existed here nearly 400 years ago before English settlers arrived, including the bird, tree, insect, water features, and other wildlife that would have populated this area. Created using 3-dimensional audio, the walk provides a sonic experience of this ancient spot. As Boston harbor was filled in over the course of many years, the old "back bay" would have met the land right at the west edge of modern Boston Common where a dense salt marsh bordered the area between the land and the harbor.

They're All Talking

They're All Talking

“Sonder” is an ancient viral hit — a 2010s neologism coined by John Koenig to describe “the realization that each [...] passerby is living a life as [...] complex as your own”. They’re All Talking repurposes Koenig’s now-cheesy term into a soundwalk, merging it with language and the chronology of Boston. Samples of Native American languages, English and the various languages spoken through waves of immigration are specifically tied to locations around the pond, building a linguistic timeline in the city. The incredible language diversity in the Boston area fuels a phone-in-pocket soundwalk that only allows eavesdropping on languages a listener speaks. The multilingual soundscape leaves one very simple impression of most of its conversations: that everyone, just like you, is talking, talking, talking. Presented at the ICMC 2025.

Traces

Traces

Let your route be arbitrary. There is no particular place you need to be. Feel free to sit down and rest whenever you'd like. If you move through the Common in a non-goal oriented way, the score will stay with you and shift based upon the path you choose and wherever you end up. #### Traces (2025) A soundwalk for Boston Common *What happens when we change the soundtrack of a place we think we know?* Traces is a user-guided geolocated soundwalk through Boston Common that invites listeners to imagine the history of an iconic landscape through a radically altered composition of the park's sounds. A musical composition of electronically processed field recordings, found sounds and archival recordings are woven into a lush soundscape designed to deepen perception of this historic place. By shifting our attention from sight to sound, Traces offers a spherical experience of place, rather than a linear one: a layered sonic architecture where personal associations and echoes of history are omnidirectional. Rather than telling a fixed story, Traces amplifies quiet voices and ephemeral impressions, making the participant both witness and storyteller. In the private seclusion of headphones, listeners move through the park, free to wander and imagine—remapping The Common on their own terms. Traces offers us a chance to slow down, listen, and discover our own relationship to the unseen contours of a public space.

Tandem Running

Tandem Running

Tandem Running utilizes both synthesis and manipulated audio recordings to portray the involvement of invertebrates at every stage of plant life from pollination to decomposition. It specifically recognizes invertebrate species typically seen as scary and/or unappealing, such as wasps and worms, whose contributions to the ecosystem may go unappreciated, but are nonetheless critical for allowing human-planned natural spaces like the Boston Public Garden to thrive. Different species found in and around the Public Garden are represented both literally, with manipulated recordings of the sounds they make, and metaphorically, with melodic and rhythmic elements that become denser and more musical as points of interest along the route are approached.
