Radio Art Zone # Christina Ertl-Shirley: Salix matsudana Tortuosa ▾

22 hours with the recalcitrant corkscrew willow A plot of land near Berlin on which stands a half-felled corkscrew willow (Salix matsudana Tortuosa). The tree, which was many meters tall before being cut back and often attracted attention with its "curly" branches, was planted in 1974 and had to be cut down to a 90cm trunk two years ago due to city regulations.

Passing walkers always mourn around this beautiful tree, but are also amused by its unruliness: The remaining trunk sprouts again and again and countless red-green shoots grow out of it in the most diverse variations, which then must be trimmed again immediately so that no real branches form. The trimmed tree seems more active than ever and has become a favorite habitat for insects, birds and tree fungi and perhaps other species. Its sawed-off jagged branches, which have been converted to fences, are also beginning to sprout regularly.

For Radio Art Zone, this corkscrew willow becomes a sound producer itself for 22 hours, as I sonify its biological processes, and capture the sounds of its inhabitants and environment. In this soundscape, facts, anecdotes, songs, poems, dreams, and conversations around the tree interweave and become a multidimensional narrative. For this I use material from archives, realize my own willow compositions and invite musicians, people out for a walk, poets and tree experts to stay next to the tree trunk and listen to what they have to share with me inspired by the recalcitrant corkscrew willow.

Christina Ertl-Shirley creates audio-visual narratives in the form of sound installations, radio plays, drawings, radio features, short stories, and compositions (based on field recordings and analog synthesisers). She sees her works as transmedia explorations with experimental approaches to the sharing of knowledge. She is particularly concerned with the interweaving of nature, art, and technology, immersing herself in the respective microcosms, such as the world of the animal "paper nautilus", the cultural history of the elevator, the environment of wooden beetles in the Berlin forest or the discipline of moss research.

The starting point for her work is traveling these niches through scientific, historical, and subjective material. She draws on the suggestive possibilities of these elements and comments on them through her own acoustic, visual and haptic investigations, realizing artistic narratives from them.


Radio Art Zone is a 100-day radio art station by Radio ARA and Mobile Radio for the European Capital of Culture, Esch2022. It is broadcast in the south of Luxembourg by Radio ARA on 87.8 FM. It is also live-streamed for a worldwide audience and transmitted by a network of international partners.

Elemental Foley ▾


This environmental audio stream is broadcasting live from the 'End of the World' glacier in Northern Italy's Stelvio National Park. The solar-powered listening station has been continuously transmitting since July 2025 from ca. 2.700 metres above sea level in the Italian Alps. We tune in daily to the glacier's cyclical sonic material life, allowing us to witness meltwater rhythms, sediment flows, avalanches, landslides, animal life and the seasonal impacts of weather and tourism entering the microphones, in real time. Elemental Foley by Lia Mazzari will be on show as a solo exhibition at Microscope Gallery in Dalston, London from 10 - 26 September 2026.

Radio Concrete #59 - Snezhana Reizen - Antenna ▾

Introducing a special episode by Snezhana Reizen.

Antenna. The madness of the day...

Antenna is a series of works on transduction with the sole sound source taking place - radio waves. Here I was devoured by discontinuity and discharge inherent to the "miracle of the wireless. the omnipresence.. the overleaping of frontiers” - the radio, like it was marked by R. Arnheim.

This piece emerged in two phases: the first one can be called a transduction - a process of conveying potential energy from discharge into a signal. It was a spontaneous live radio-noise set recorded close to the closed shelter. This summer
I found myself stuck in between absence and presence in amplified senses,
confronting the avalanche of the noises erupting on us by this world, facing the chaos, “embracing alienation”, holding a degree of disbelief..
that this "disparity can be modulated”..

Yet, seeking the perceptual transmutation.

Biologists say there are two phases for the perception, so that after transduction of the signal, a transformation should take its place.
Following this logic, the second phase of this work appeared as an improvised procession with effects and filters - a real-time mix-ture, with slight subsequent recombinations.

If there's something one can call a ground for this piece, besides its sound source, it dwells upon a chance. It is a conversation with a present moment beyond the borders by a flying carpet of propagating radio waves.

"Antenna" was created drawing on ambisonic spatialisation with a mixed approach, so that some sounds move through in a chaotic manner, while the trajectories of others were meticulously calibrated. In doing so, I did not seek to determine the exact location or direction for each sound particle, but rather to underline the traces - their nomadic movements within the whole sphere of the revealed ensemble.


Radio Concrete by Hagai Izenberg is a monthly experimental radio show focusing on live mixing and processing of field recordings together with contemporary music and soundscapes.

Gravity Waves and The Spirit World # Emergency Broadcasts ▾

In the first hour, Gravity Waves: a mix which centres around a lengthy track by Lacrima called The Horror is Your Open Mouth, framed with tracks by Melinda Bronstein and some remixes by Nicholas Langley (aka Hz), from his reshapes LP on Third Kind.

In the second hour, Spectral Transmissions: Emergency Broadcasts. Emergencies happen every day in the UK and across the world. They can be caused by severe weather or other natural hazards, by deliberate actions, or as a result of accidents or infrastructure failure. They can be events that happen quickly and are over in a few hours, or they can develop and continue over the course of several days, months, or sometimes even longer.

The situation is once again becoming very uncertain. Automated telephone, fax, e-mail and text messages will be sent. The Emergency Network broadcast system will be activated. Site Sirens will activate. SIRENS will sound. Page not found. Unfortunately the requested page could not be found. This might be caused by a recent update to our website. Please go to our homepage to find what you are looking for. You can listen to news on live radio to find out about the emergency. Make a plan.


Commissioned new work from contemporary sound practitioners and other audio choices from experimental electronic collective The Spirit of Gravity.

tekhnē #3 - Abigail Toll, Yann Leguay, Gauthier Deplaude & Rodolphe Bourotte ▾

This third episode features four artists who took part in a research residency at GMEA (Albi, France) as part of the Tekhnē, initiated in 2023:

  • Gauthier Deplaude in an informal discussion with Benjamin Maumus about his project Horloges etc.. This work uses two quartz clocks and their electrical environment as the sole sound sources, within a unique technical setup created by the artist, without effects or attempts at control.

  • Rodolphe Bourotte tested his latest music production software, COMMA, during his residency. He engages in an informal discussion about his program and insights from his residency week.

  • Yann Leguay shares an anecdote about one of his early projects, Dead Media, which centered on reversing the recording process in a vinyl pressing factory in France that has since closed. He reflects on the notions of trace, media, and collective memory.

  • Abigail Toll presents Where Words Fail: World Building With Data, Sound, and Co-creation, a sound and interdisciplinary visual study that explores algorithmic herd behaviour in nature and its connections to surveillance practices.


Bi-monthly insights into the activities of the European project tekhnē, which started in 2023. The series showcases a selection of artists who share and discuss their work and listen to recorded material. By putting the focus on the user rather than the developer, this project aims to explore the emancipatory potential of technology in music and sound art. Technology as an art of craft, appropriating and transforming existing tools, to imagine multiple ways of creative misuse. tekhnē is a collaborative project, co-funded by the European Union.
