Saturday, December 6th, 14:00 - 16:30


Experience an extraordinary musical journey with the duos Reinhold Friedl – Jørgen Teller and Halla Steinunn Stefánsdóttir – Jakob Riis. Both ensembles present brand-new works developed through intensive rehearsals, on Falster and in Malmö, during the days leading up to their performances.

This unique event takes place in the impressive Great Hall at Biblioteket Rentemestervej, where quadraphonic acoustic music will enrich your Saturday afternoon.

On December 6th at 14:00, you are invited to immerse yourself in shifting sonic landscapes as these remarkable artists merge classical sensibilities with contemporary sound worlds. It is a rare opportunity to hear experimental duos of international calibre—four musicians exploring the spatial and sculptural dimensions of sound in their own visionary ways.

With tickets priced at only 20 DKK, you can enjoy an inspiring and fully immersive concert experience, where sound moves freely around you and invites deep listening.

Secure your ticket at BILLETTO today and experience EARSOUNDSCAPE at its finest.


The Copenhagen musician Jørgen Teller released a solo guitar album in 2022 titled Berlin, a collection of intensely concentrated, brittle, scraping-and-plucked explorations on a prepared guitar, itself an objet trouvé discovered on a street in Kreuzberg. The Berlin-based head of zeitkratzer, Reinhold Friedl, picked up the thread. Already known for his uncompromising inside-piano techniques, he initiated a risky and daring collaboration: six guitar strings paired with more than 200 piano strings.

As Teller is also an electronic musician, he expanded the setup with live, real-time quadraphonic spatialization, a bold string-play in 3D.

Imagine objects gliding across strings, a heavy piano lid wide open, resonances trembling beneath. Guitar splinters erupt from complex sound-surfaces; E-bows sing; rich overtones shimmer. The guitar shifts between quiet companion and commanding protagonist, its bass strings tuned deep, raw, harsh. The piano reflects that same fluidity: tactile, unfamiliar objects excite its strings and coax out odd resonances.

Breathing four-channel spatial dialogues emerge, unexpected, humorous, bright, sometimes brittle, suddenly sharpened by bursts of crystal clarity. Sound becomes motion. Space becomes tension. And always, the strings remain the essential sonic ground.


Breath of Directions is a composition for violin and electronics: a violinist in real time, a four-channel tape part, and quadraphonic live processing that turns the room itself into a resonant instrument. The work draws on the Pythagorean idea of a cosmic breath, sound understood as a living, vibrating geometry. The quadraphonic field becomes an invisible lung that expands and contracts around the listener. Pulses arc between loudspeakers; tones merge into delicate interference patterns; brief flashes of clarity appear and dissolve.

The Icelandic violinist Halla Steinunn Stefánsdóttir, known for her boundary-defying approach to contemporary performance, brings a playing style that merges precision with rare physical sensitivity. She moves fluently between early music, experimental practice, and spatial listening. Her approach draws out the violin’s grain, breath, and fragile resonances, treating sound as tactile material, alive and poised on the threshold between control and release.

Working at the intersection of live electronics, spatial audio, and improvisation, Jakob Riis has long explored how algorithmic processes, real-time transformation, and multichannel diffusion can shape sound as a moving, shifting architecture. In Breath of Directions, his quadrophonic processing extends the violin into space, stretching, refracting, and reshaping its tones into a breathing sonic geometry.
