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

Ursula Winterauer, also known as Gischt, is an experimental composer, electronic music producer, and curator based in Vienna. Her eclectic sonic landscapes offer nuanced interpretations of industrial, techno, and ambient genres, shaped through the use of bass guitar, synthesizers, and swirling clouds of electro-smog.

In her works she generates raw sounds between brutality and atmospheric diffusion sometimes in contrast to the clear and human nature of her own voice used as an instrument. She is the bassist of the doom metal band Eaeres and forms one half of the noise-duo The Answer is No alongside Maja Osojnik.

Winterauer works as a sound designer and composer for film and develops compositions for contemporary dance, is co-founder and label boss of Ventil Records, co-organizer and commercial director of the Unsafe+Sounds Festival and was the curator of New Salt – Festival for sonic exploration & digital art in 2024.

Daniel Haas – mostly known as Sturmherta – is a musician, sound artist, and experimentalist who focuses on related fields such as digital synthesis methods for sound design, chaotic systems, and the translation of sound waves into different domains, making them visible, tangible, or experienceable in other forms. He experiments with sound as a mechanical force and as a physical phenomenon in space. His works take shape as performances or installations that merge the visible and the audible, playing with the limits of human perception through stimulation or deprivation. They deliver intense, physical experiences, often through raw and brutal sonic constructions or glaring light and imagery that challenge and overwhelm the mind, or leave us in total darkness – suspending the audience between sensory overload and absolute void, and pushing them into states of heightened awareness and altered perception.

Kraken
Kraken is an experimental software instrument built on a chaotic cross-feedback modulation system. Multiple oscillators merge into a complex synth voice that constantly reorganizes itself. Even the smallest adjustments can provoke drastic transformations, as every element is tightly interconnected. Instead of aiming for predictability, the project explores instability as a creative force—shifting between dense noise textures, fragile microtonal clusters, and emergent rhythmic fragments.

For this performance, Kraken is specifically adapted to the acoustics and long reverberation times of the Marien Dom, engaging directly with the space itself.
