Performance

Upsammy

As electricity blossoms and leafs glisten, upsammy creates interpretative space, cleverly paradoxical in its concurrent comfort and desolation. With a keen ear for crystalline melody and intricate rhythm, her music sculpts a certain perpetuity and spatiality, sliding across tempo scales, while retaining an organic touch as a gentle hum of nature digitized. During her live shows she creates kaleidoscopic terrains built from micro textures and field recordings, fluidly mixing between inner and outer environments.

Having studied Image and Media Technology at the Utrecht University of the Arts, Thessa Torsing (real name) is intrigued by the rhythms and vibrational qualities of her surroundings, shaping a singular aesthetic that blurs the synthetic-natural divide.

Since 2017 Torsing has released a string of singles and EPs on labels Nous’klaer Audio, AD93 and Die Orakel. Her gift for full-length composition is showcased through her albums (Wild Chamber, 2019) on Nous’Klaer Audio, (Zoom, 2020) on Dekmantel, (Germ in a Population of Buildings, 2023) on PAN and (Strange Meridians, 2024) on topo2.

Joy Guidry

Joy Guidry is a bassoonist, versatile improviser, performance artist, and composer of experimental, daring new works that embody a deep love of storytelling; Joy’s music channels her inner child in honor of their ancestors and predecessors. The San Diego Tribune has hailed her performances as “lyrical and haunting…hair-raising and unsettling.” Joy was born in Houston, Texas, into a creative family that has shaped who she is today.

Joy has presented her original work at The Metropolitan Museum of Art, Whitney Museum for American Art, Hauser & Wirth, Museum of Contemporary Art San Diego, The Kitchen, Redcat, among many other venues. She has been featured in festivals like the La Biennale di Venezia, Banlieues Bleues festival, A'Larme Festival, Cologne Jazz Week, Dripping Festival, Spoleto Festival USA, Big Ears Festival, and many more.

Madeline Stepien

Madeline Stepien is a composer and sound artist based in New York City.

Her compositions and performances examine phenomena of artificial sound via digitally constructed environments and various modes of synthesis & electroacoustic manipulation. Through these techniques she dissects, reconstructs and subverts the aesthetic and political value of the "unnatural".

Operating under the alias "pent" from 2020-2024, she developed her practice through a plethora of live performances & recorded material that range from live interventions in club environments to fixed media installations.

Sean Meehan

Drummer Sean Meehan began performing during the late 1980s at the Amica Bunker series for improvised music, located at the Anarchist’s Switchboard and later ABC No Rio in New York City. His work has been presented at some of the most prestigious venues for new music including the Instal Festival (Glasgow), The Whitney Museum's Biennial (New York), Lincoln Center (New York), and Goethe-Institut (Hanoi), but he primarily performs at small, informal spaces and artist-run festivals. For nearly twenty years he and Tamio Shiraishi presented their summer concert series, always in different interstitial locations throughout New York City. Three of these concerts have been documented on LP on the Fusetron and GD Stereo labels. Meehan's most recent project was a highly abridged audiobook of Hermann von Helmholtz’s seminal text from 1863, On the Sensations of Tone, and Magazine (Sacred Realism, 2022), a piece for solo cowbell. Meehan was a 2020 recipient of the Foundation for Contemporary Arts Grants to Artists Award.

Raven

The enigmatic Bay Area producer Raven will be joining us to share METAPHYSICAL BLUES.

“I’m trying to, in a sense, capture what I see moving around in San Francisco. For example, when it rains, I like looking at the reflections of light on the pavement, watching water roll down a hill, or architecture, skyscrapers and things like that… I’d like to think that I portray what I see when I’m walking around.”

Raica

RAICA is a live ambient electronic project focused on slow evolution, texture, and spatial depth. Built around hands-on hardware systems, performances unfold gradually, emphasizing tone, resonance, and subtle rhythmic drift over fixed structures. 

Travel Agent

Travel Agent is a collaborative project between Cameron Kelley and Ruben Griggs. The two channel over a decade of shared conceptual development to synthesize boundless electronic music. Though no sound is off the table for Travel Agent, the music tends towards the textural, dubwise, and hallucinatory. This is music of possibility, opportunity, initiative.

ANKOKU

ANKOKU is a merging of movement, sound, light, healing, and earth practices between jade wong and hana shiozaki. Together, they create containers that induce presence for performer and audience, relying on chance and play for the work to emerge. ANKOKU has performed at the Salish Sea Butoh Festival, CO- Show12, and Teatro de la Psychomachia.

Installation Art

Blazinspace

Blazinspace has been an evolving series of live performances and art installations. Rock shows, movie remixes, surreal jazz nights and raves. It’s an exploration of sharing space with other people; both inner and outer. Music wakes up images in me and projectors have a way of reminding me that we are all made of light. When I think of all the wonderful ephemeral moments live musicians have given me that echo still; I’m so honored I get to bring what filmmaking has inspired in me to meet them in the moment. To tell a story, to saturate the space. I believe that people are more important than profits, that we need to grow with our hearts in mind, and that Art is the antidote. 

Carlos Tulloss of Afrocop writes “I don’t think people realize how much work goes into these visual performances. It is such a special thing that they bring to these events. It is the equivalent of a super high budget production every outing, making these local shows something you won’t see anywhere else. Go see Blazinspace every chance you can, the shows are constantly evolving.”

María Dolores A. Matienzo

Simone Pierson

Simone is a Ground Hum organizer and maker who walked past a scrap pile and saw a sculpture. Her installation was born from a chance encounter with a mangled piece of chicken wire. By applying fiber techniques to industrial salvage, she transforms rigid wire into organic, hand-knit forms that aid in way finding and ambiance for this years’ Ground Hum Festival.

Workshops

We will be conducting workshops at Washington Hall from 12:00pm until 3:30pm. 

Worldbuilding & Live A/V Performances with i+eo

Live audio-visual performance is more than syncing sound to image. It is the act of creating immersive experiences; it is worldbuilding in real time.

Drawing from their recent performances and works in progress, i+eo, an a/v duo composed of IHA and ephemeral objects, invites attendees into their evolving approach to sonic and visual worldbuilding and behind-the-scenes processes. Topics include incorporating inspiration, working collaboratively, moving from ideation to conceptualizing an artistic identity or project, embracing play and experimentation, and navigating intuition and structure for an a/v performance.

This session focuses on process and trust in collaborators, your artistic voice and contribution, and the experience of performing live. Come with a curiosity and willingness to imagine new worlds together.

Performance-oriented stochastic MIDI sequencing with CAMI FLAGE

Cami Flage presents the Quartermaster (QM), her custom performance-oriented stochastic MIDI sequencer. Cami will share some fundamentals of stochastic sequencing, share stories of the QM’s evolution since 2019, and offer insights on research & development as part of the electronic musician’s journey. A Q&A will follow the presentation.

i+eo

i+eo is an audiovisual and DJ duo composed of IHA and ephemeral objects. They create immersive, otherworldly performances that unfold as sites of transformation and reflection. Through evolving soundscapes and vivid, morphing abstract visuals, live-mixed from generative processes and real-world footage, they construct speculative worlds that exist somewhere between memory and futurity.

Rooted in the West Coast of Canada’s underground electronic music scene and shaped by their shared experience as queer Southeast Asian diaspora, i+eo’s work explores identity, fiction, and imagined futures. Their sound traverses ambient, techno, bass, dubstep, and broken rhythms, guided by curiosity, play, and mystery. Following their selection for MUTEK’s inaugural Incubator program (2024), i+eo premiered Portals at MUTEK Montréal (2025).
