Aurelien’s unique work involves using contact microphones and modular synthesizers to co-create music with the sounds of melting Alpine glaciers.
The Glacier as the Ultimate Studio Partner
After two decades in band music, Aurelien transitioned to electronic music during the COVID-19 lockdown. He sought to root his new sound in the natural world, moving beyond traditional sampling to a direct, improvisational partnership with nature.
“I didn’t just want to record the sounds to edit and sample them later. I wanted to make music with the glaciers, as if the glacier was a partner,” says Aurelien.
This collaboration involves placing hydrophones (underwater microphones) and contact microphones directly into crevasses and glacial streams. The resulting sounds—the cracking of the ice and the flow of subglacial water—are fed into a modular synthesizer, where envelope followers ensure the glacier’s sonic activity directly shapes the musical output. This process results in unique, real-time compositions.
The Science of Perception
Aurelien emphasizes that the extreme environment, despite its challenges, is the “most beautiful recording studio” he has ever used. The rapidly melting nature of the glaciers adds a sense of urgency, often leading to “happy accidents” in the limited time available.
He also notes that specialized audio technology is crucial because many of the glacier’s most “precious sounds” are too quiet for the human ear. Tools like geophones and hydrophones act as an extension of human perception, allowing these subtle natural sounds to be brought into our consciousness.
Reliable Gear in Extreme Conditions
Operating in these harsh, often sub-zero environments demands exceptionally durable and reliable equipment. Aurelien has relied on Austrian Audio’s professional headphones since the inception of his project.
“Working in this environment, my gear needs to be robust. The Austrian Audio headphones have been with me from the beginning of this project and have truly passed the test of time under these extreme cold conditions,” Aurelien notes.
Global Recognition and Future Projects
Ghost In The Loop’s pioneering work has garnered international attention, including an invitation to speak and perform live at the United Nations Ocean Conference.
A documentary detailing Aurelien’s work and creative process on the glaciers is currently in production and is expected to be released in late October.
