- MAN REI / STEFAN TIEFENGRABER
- 10.10.2025
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
October 10th
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.

Exhibition Opening

Opening hours
18th – 21st June 2025
Wednesday – Friday 3 – 6pm, Saturday 11am – 2pm
In her performative and experimental film practice, Daniela Gutmann
explores how the gaze can emerge not merely as an abstract act of
vision, but as a bodily, affective, and relational gesture. Through
choreographed encounters and filmic stagings, on the gesture of the gaze
investigates how filmmaking itself becomes a performative process—where
movement, camera, and perception intertwine.
At the heart of her work lies the interplay between the body—as a vessel
of gesture, presence, and motion—and the medium of film, whose apparatus
carries a physicality of its own. The gaze, in this context, is not
fixed or unilateral but shifts across bodies, frames, and positions of
power. Seeing becomes an embodied act; the camera, far from neutral,
participates in this gesture.
Film is not approached as a finished image, but as an open, experimental
field—a space where modes of looking, representation, and relational
structures are questioned and renegotiated. Gutmann’s practice
foregrounds a sensuous and critical engagement with the medium, seeking
poetic forms that challenge dominant visual regimes.

Daniela Gutmann is working in the field of experimental film,
performance and installation.
Her interest lies in the tension between physical conditions, sensual
perception and its alienation.
She works with analogue material, bodies, ice, dust, noodles, latex and
words.
She lives and works in Linz, Austria.

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.
