- OSCILLOSCOPE MUSIC
- 09.05.2025
The Wavering Worlds series goes on an excursion. Since bb15 moved to its current location, there has been a desire to organise an event in the New Cathedral opposite. Due to the special architecture and acoustics of this building, it can provide an impressive setting for the staging of experimental music and that is exactly what we intend to do. Over four evenings in 2025, a selected group of artists will explore the specifics of the space and develop site-specific settings for their sound performances.
Meeting place is the north entrance of the New Cathedral (Mariendom) next to the tower.
Doors open at 6:45pm
Concert starts at 7pm sharp!
No entry after the start of the concert

OSCILLOSCOPE MUSIC
Oscilloscope Music is the audiovisual project by Jerobeam Fenderson and Hansi3D where images are drawn with sound. The glowing green line drawings took the internet by storm in 2016 when their first self-titled album came out, and they released their second album N-Spheres in late 2024 on floppy disk.
In their live shows they have upgraded from analog oscilloscopes to high-speed multi-wavelength lasers, sending the audience on an omnisensoric interdimensional geometric space experience.
Oscilloscope Music consists of Jerobeam Fenderson and Hansi3D.
Jerobeam Fenderson is an audiovisual artist and electronic tinkerer based in Vienna, Austria, who likes drones, lasers, computers and cats.
Hansi3D grew up in Austria, he still lives there. He really likes math, music and programming so making oscilloscope music has become the perfect rabbit hole for him.

SAINKHO NAMTCHYLAK / ANDREAS TROBOLLOWITSCH
Trobollowitsch and Namtchylak create a sonic landscape where the primal and the contemporary converge. Namtchylak is known for her mesmerizing voice and her use of traditional Tuvan throat singing in diverse musical contexts, ranging from jazz to contemporary and electronic music. Together, Trobollowitsch and Namtchylak form a duo where the mechanical and the human merge in unexpected and often hypnotic ways.
Their collaboration reflects the intersection of different cultures and sounds, offering a fresh perspective on the blending of diverse influences.
Sainkho Namtchylak is a Tuvan-born singer, composer, artist, and teacher known for her extraordinary vocal range and emotional depth. Drawing from the cultural traditions of her homeland, she creates powerful links between the archaic and the avant-garde. Based between Europe and Asia, she has released over 60 albums, authored two books, and has been a prominent voice on international stages since 1987, performing at major festivals for jazz, world, and experimental music. Alongside her musical work, she also presents her visual art in exhibitions and art fairs across Asia.
Andreas Trobollowitsch is an Austrian composer and sound artist whose work explores the intersection of concept, material, and movement. Using prepared instruments, modified objects, and kinetic systems (like melting ice or rotating motors), his pieces emphasize timbre, space, and the physicality of sound.

mʊdʌki
For Wavering Worlds 101020 mʊdʌki unfolds an immersive live set based on the almost floating sounds of the medieval hammered dulciner. The gentle tones become increasingly intertwined with experimental digital soundscapes – a dense composition between electro-acoustic experimentation and pulsating technological sound aesthetics. The result is an interplay that is both contemplative and futuristic.
Polina Khatsenka aka mʊdʌki is a czech-based sound artist, dj, event organiser and music producer from Minsk, Belarus. She has devoted her work to sound exploration since 2015. Her music production is arising from subconsciousness with an accent to authentic sound sources, author‘s recordings with usage of basic/primitive hardware, including diy synths, all based on digital setup. Each type of performances of hers are amplified by improvisational methods with space for randomness left in order to make each show bear peculiar energy and provide the listener an intensive feeling of living the moment.

MAN REI
Man Rei will perform material from their recent works and releases, using a sampler, vocal looping and electric guitar, adapting the already reverb-heavy production to the grand acoustics of the New Cathedral Linz.
Man Rei is a music project of Kristin Reiman, a Frankfurt-based Estonian musician and artist weaving ambient alt-pop from blurred samples, choral arrangements and hazy instrumental loops.
Their recent work, including their latest album Thread (2024), is released on Somewhere Press. Reiman also runs a regular radio show called An Awkward Guest on Noods Radio.

STEFAN TIEFENGRABER
Stück für eine Gitarre [concert]
Tiefengraber will perform an adapted version of his installation work Stück für drei Gitarren for Wavering Worlds in the New Cathedral in Linz. He will work with a multi-channel set up and use live produced powerful guitar sounds that are going to meet precisely placed sound interventions. The reflections of the walls accompanied with precisely controlled feedback will merge to a new composition – a choreography of sound, material, and space where kinetic tension becomes aural expression.
With this project Tiefengraber explores the interaction between mechanical systems, resonant bodies, and architectural acoustics in real time.
Stefan Tiefengraber lives and works in Graz and Linz, Austria. His work ranges from kinetic sound installations to audio-video noise performances and experimental film. Tiefengraber experiments with the modification of devices, which are originally manufactured for different purposes. Combined with the perception of the audience, this experimental attempt of exploring old and new materials leads him to new and unpredictable results.

Dear Maja, Mette, and Saffi,
Have you ever heard of the office monster?
It’s said to be a strange creature that haunts administrative spaces – obsessed with formalities, decision-making processes, and the supposed logic behind them. It spreads boredom like spores, controlling things in mysterious ways, or perhaps not understanding anything at all.
I thought this might be something fun (or terrible) to explore.
I see you all as critical minds, each with a quirky edge. When I imagine the three of you together, I hear weird sounds, see odd creatures, mumbled narrations, characters pretending to fit into a certain narrative (but, actually, they don’t). There’s an openness to collecting strange objects or thoughts, and no fear of putting out too much.
We should look together for this species or non-species, one of these monsters from an office setting by imagining a narration around it in an exhibition.
Why? Art spaces often feel too clean, too sterile, and I kept thinking of the office monster there – lurking, silent, not doing much but still managing to spread despair. We’ve all met versions of it. I don’t want to embody or illustrate one of those creatures. We could create a space that pushes back against that feeling of being trapped by bureaucracy, all-too-trying to be smart, and decisions that seem so rational but are so dangerous. I’m not entirely sure what this means yet, and maybe that’s the point. But it could set a mood. And maybe then it comes together as one in the space, or it at least serve as a circus against bad moods. Who knows. In Linz.
I imagine the exhibition like a theater piece in three acts: each of you telling a story. One might confront the monsters. One might decode their past. One might show the quiet damage they cause. There could be a prologue, a backstory of how the monster came to be, how it inhabits the office, or what it leaves behind.
I’d love to hear your thoughts. Maybe we can find a cure for office spaces.
Maximilian
The exhibition is supported by Slowenisches Kulturinformationszentrum SKICA, Vienna, and partly made possible through financial support from the Mondriaan Fund.
