Passages of the Past

A tour through Salem, guided by Nathaniel Hawthorne, sharing his stories, his inspirations, and the many ghosts of Salem. Encounter the characters he created along the way that have endured in American culture for centuries, and perhaps discuss them with the muse of his psyche. This tour can be enjoyed 24/7 as all locations are on public property. You will start your walk on Turner St, travel down Derby, up Hawthorne Blvd, across Essex St, through PEM Walkway and end on Charter St at the Old Burying Point. This tour does not start and end in the same location. This tour works best when it is downloaded to your phone and while it's great anytime we love it best at night. This tour was made possible by a grant from the Salem Cultural Council and the support of the House of Seven Gables.

Sound on Mystic is an outdoor audio installation combining music, spoken word, sound art and ambience into an immersive experience. It is located along a two-mile stretch of the Mystic River in Medford and Arlington, Massachusetts, and is accessed through ECHOES, a free mobile app that uses GPS data to cue different sounds at various sites. Once you download the app, just put on a pair of headphones, take a walk within the installation’s extensive boundaries, and you'll hear a diverse set of sound works that are all united by the river itself, and its complex legacy as a place of history and nature, community and conflict, labor and recreation. *Access Instructions:* 1. Install the ECHOES app (the link is below, skip to step 3 if you've already found the walk in ECHOES) 2. Search for "Sound on Mystic" inside the app 3. Download the walk (this will function better than streaming the walk) 4. Close out other apps on your phone that access your location and may interfere with ECHOES 5. Go to the river and open the walk. You will see a map with areas highlighted in blue. As soon as you enter a highlighted area, sound will automatically begin to play. Depending on how fast you walk, some pieces will overlap with each other, or some pieces will play completely leaving a period of silence. Don't worry, that's all just part of the experience -- enjoy! Sound on Mystic is created by Ian Coss, Dwayne A Johnson, and Gary Roberts, with funding from the Medford Arts Council and Arlington Cultural Council, and support from the Mystic River Watershed Association.

**_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 🧡

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.

Can you find where the Great Elm Tree of the Boston Common once stood and discover the ghost stories along the way?

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.

Take this unique tour of Davis Square and learn of weird beasts and odd occurrences! You never know who--or WHAT--walked the spots you're standing in. This is a special production by the Post-Meridian Radio Players, to help celebrate ArtBeat and all that is unique and wonderful about Somerville. For more information you can visit us at pmrp.org .

**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)".

River Listening is an interdisciplinary project that invites participants to explore the hidden acoustic ecologies of waterways through an immersive, technologically mediated listening experience. Drawing from a decade of hydrophone recordings and scientific research, this soundwalk transforms the site into a dynamic sonic environment that reveals the rich life beneath the water’s surface. Hydrophonic Discoveries is an immersive soundwalk that reflects on the project’s last decade of work and unveils the hidden acoustic ecologies of river ecosystems through cutting-edge underwater sound recording technologies. This interdisciplinary project transforms scientific research into an artistic experience, inviting participants to explore the soundscapes of global river systems. Drawing from over 300 hours of hydrophone recordings collected from global river systems, the soundwalk bridges art, science, and environmental awareness. The artistic outcomes from River Listening are central to our public engagement efforts, which include soundwalks and live-streaming hydrophone arrays. These artistic projects have contributed to the advancement of scientific recording techniques and ecoacoustic methods. The River Listening project has presented over 35 soundwalk projects on the Echoes platform since 2014 and was an early adopter of this platform.
