Between Nature and Machines
Our daily audible environment is a continuum just like that. What could illustrate it better than browsing the areas of Forum Acusticum 2026: from bioacoustics to industrial vibration, from music to speechâsounds we perceive and sounds we make. Artistic expression responds to the full spectrum of that reality, within various musical traditions and beyond.

About the pieces
Off the Rails
Off the Rails is an acousmatic composition based on recordings of a heritage steam railway in rural Austria. It uses composition as a means of articulating personal observations of the recorded sceneâobservations that may otherwise remain inaccessible to listeners of field recordings.
Re-listening to a recording can evoke lived experience in the recordist, yet that experience does not reside in the recording itself. This creates a perceptual divide between artist and audience.
By composing with and intervening in the material, I guide the listenerâs attention towards particular details. Sonic transformations introduce further dimensions of my listening, including the use of ultrasonic material. The pieceâs form relates to the idea of flow, referencing the rushing-by of the train.
INSIGHTS INSIDE MACHINES I
At the heart of this self-built instrument are two motors with makeshift propellers and attached contact microphones, extended by a laptop that generates a feedback loop. The motors run at the very edge of their driving force. Will they complete a rotation, or stall after a brief halt? Here, itâs the motors that hinder themselves: the motorâs audio signal alters the speed of the oscillator driving it, which in turn changes the audio signal again. This lets the motor accelerate itself but also block and repeatedly stall itself. Once turning, you find yourself following this forward motion, made visible through live video projection, only to be thrown off again and again, as the rhythm shifts.
Serendipity 512/2600
What happens when you look for something without knowing what you are looking for?
Serendipity 512/2600 is an improvisation with two replicas of the ARP 2600 semi-modular synthesizer. Rather than working towards a predetermined result, I use repetition and familiarity with the instruments to build a framework in which something unexpected can occurâan approach, not an outcome. The four outputs of the synthesizers are spatialized in quadraphonic sound and simultaneously drive an overlaid XY-scope visualization, so the sound becomes directly visible as it unfolds. By interweaving the channels, different relationships between the two synthesizers produce continuously changing visual forms.
Serendipity cannot be produced on purpose. It can only be noticedâoften only in hindsight, sometimes by the performer, sometimes by the listener. The piece asks less âdid something happen?â than âwho gets to recognize it, and when?â
About the artists

Benedikt Alphart (*1998) is a composer, sound artist, and curator based in Graz, Austria. His recent work often engages with âinaudible soundsâ: sounds encountered in remote places or situated beyond the perceptible range of the frequency spectrum. His artistic output encompasses acousmatic, instrumental, and audiovisual compositions, as well as sound installations, which have been presented internationally. Alongside his artistic practice, Benedikt Alphart has curated the concert series KULTUM â Neue Musik at the Kulturzentrum bei den Minoriten in Graz since 2023.

LEKO Quartet brings together four musicians from Ukraine, TĂŒrkiye and Latvia, united by jazz and a shared interest in improvisation, interaction and musical storytelling.
For this programme, the quartet explores contrasting perspectives on the human experience within a modern, urban world. Take the A Train, made famous by Duke Ellington as the signature of his orchestra, evokes the pulse of the city â movement, rhythm and infrastructure, almost like a musical machine in constant motion. In contrast, Nature Boy turns towards the individual: a mysterious wanderer whose journey leads to a simple yet universal insight into the importance of loving and being loved. Beautiful Love continues this human perspective from a more immediate and emotional angle, exploring love, longing and vulnerability.

Ina Thomann is an electroacoustic composer and sound artist based in Graz, Austria. Trained in Computer Music and Sound Art at the University of Art in Graz, they are currently pursuing a Doctorate at the Center for Artistic Research on the potential of duration in compositionally performative sound installations. In 2025, Thomann was awarded the âStaatsstipendium fĂŒr Kompositionâ by the Austrian Federal Government, and several of their works have received funding from the SKE Fonds. Their practice is conceptual and research-driven, rooted in self-programmed sounds, field recordings, and self-built instruments. Their work has been presented internationally, including in Detroit, KrakĂłw, Stockholm, Vienna, and Graz.

Joseph Böhm is a sound artist, researcher and musician working between improvisation, electronic music and experimental performance. His practice explores experimentation, participation and interaction between sound, technology and space.
