WANDELBAR - WINTER 2026
This project explores the boundaries between acoustic instrumental sound and its transformations through electroacoustic processing. Sound is transformed into an augmented sound object.
Our duo transforms into a laboratory dedicated to sonic mutation. The instruments thus appear as modular, constantly evolving sound bodies, oscillating between acoustic presence, electronic projection and conceptual reflection.
The programme covers a broad sonic spectrum: from solo pieces with or without acoustic sound processing to a composition in which the viola and saxophone are transformed into loudspeakers.

WERKSTÜCK - FALL 2026
This interdisciplinary research project brings together music, the visual arts and traditional craftsmanship. Historical textile production techniques are reinterpreted through contemporary sound art and performance. Our artistic research explores the aesthetic and mechanical processes of craftsmanship, as well as the social and gender representations associated with it.
The Klexs duo, in collaboration with Lucerne-based artist Pia Matthes and percussionist Julien Megroz, is launching an interdisciplinary project at the intersection of music, visual arts and traditional craftsmanship. The aim is to transpose and reinterpret historical craft techniques within contemporary sound art and performance formats.
Pia Matthes has been interested for years in the aesthetics and cultural narratives of traditional craftsmanship. In her works, she transposes these into new artistic contexts – as, for example, at the SoundArt festival in Dreilinden (2024), where she developed, with March for Jacquard, a work based on historical weaving patterns.
The collaboration between the four artists continues this exploration in the field of textile production and also incorporates the mechanical and motor aspects necessary for such production.
At the heart of the artistic research lies the transposition of structures, movement sequences and manufacturing processes from textile production into sound, composition and performance.
The artistic result is an installation (open to the public) that is at once an instrument, a sound box and a visual space. It is developed as part of a collective working process and forms the performative core of the project.

ABSURDITÄT
Beginning 2026
Absurd – a word that perfectly describes our times. Between global crises and tensions within artistic circles, this project explores the mechanisms of the incomprehensible. Instead of political slogans, we use playfulness and humour, combining music and performance in a quirky and enigmatic universe.
Absurdity is not only a reflection of the world here, it is also a tool: with a wry smile, it offers us a space for reflection. The programme features two creations by Felix Nussbaumer and Gemma Ragués Pujol, accompanied by works by Peter Conradin Zumthor and Georges Aperghis, Charlotte Torres and Carola Bauckholt.
