Gretchen Jude is a composer and sound artist from Salt Lake City, Utah. We spoke with her while she was in Tokyo, where she was on a fellowship, she has lived and worked in Japan many times over the years.

For Flow, she worked on Segment 17 of the River Lech, near Pitzling, a stretch that the scientists describe plainly: heavily modified, widely lacking natural geomorphic dynamics, not a candidate for restoration. Nothing special or remarkable. A section of river that, in the grand narrative of ecological recovery, barely registers.

But Gretchen listened to the field recording and heard something the data didn’t capture: a drone. A low, persistent hum emanating from the Wasserkraftwerk — the hydropower station — that underlies the rush of water like a hidden ground note. She began to sing along with it, matching her voice to its frequencies, until she found what was there: a D-flat major triad, buried in the industrial hum of a machine converting river into electricity.

That discovery changed everything about the piece. Rather than mourning what the river had lost, Gretchen imagined something stranger and more hopeful — a remystification. What if the goal wasn’t to restore the river to a pre-human state, but to restore our sense of wonder about it in whatever state it is in?

Flow is a project by Dr Martina Cecchetto, with the scientific contribution of Dr Florian Betz and the artistic curation of Riccardo Fumagalli, in collaboration with Cities & Memory, the University of Padua (Italy), and the University of Würzburg (Germany).

Louis Möckel is a musician and researcher based in Halle, Germany. His practice sits at the intersection of experimental music, sound art, and acoustic ecology — a discipline that studies ecosystems not through what can be seen, but through what can be heard.

Elissa Goodrich is a composer, vibraphonist, and sound artist based in Melbourne, Australia. Trained as a classical percussionist, she has spent years working at the intersection of contemporary music and cross-disciplinary collaboration, including ongoing work with climate scientists and fluid dynamics engineers, turning environmental data into sound and music.
