Lemnaminor ?!   - Beginning   2023

Klexs  for  kids

Two friends meet again after a long time. An old argument flares up again and they try to settle it with their own language, in their own way. LEMNAMINOR?! - a play about friendship and communication.

For the project Image(s) we confront experimental music with light compositions by the German light artist Kurt Laurenz Theinert. In addition to self-composed music, Nils Fischer (LU), Peter Conradin Zumthor (GR) and Nicolas Gurtner (BE) will write three new works for us, which will be further developed together in various work phases: Through the lively exchange and the joint experimentation with sound and light, the works are created in a collaboration. 

In this project, we would like to take a closer look at the encounter between light and sound and experiment with how the perception of music changes through the light compositions: Does it even allow an "easier" access to experimental music? Do we also "hear" with our eyes? 

Kurt Laurenz will play his self-developed visual piano live in the venues with us. The light compositions will be projected throughout the room, so that we musicians and the audience also become part of the light art. In addition, during the concert you may make yourself comfortable on chairs or cushions or move around in the room so that you can always take in a new perspective, both visually and sonically.

Part of us - Silke - is writing her first piece for her own duo for this project. Here you will certainly be able to discover the influences of the last projects. 

For the commissioned compositions we have chosen three musicians and composers who move on the border between jazz, improvised and contemporary music. In this way, we would like to contribute to bringing these different scenes closer together.

HYPER  KLEXS  -  Fall  2024

The meeting between the Klexs Duo and HYPER DUO appeared as an obvious choice. Adept in original creations, performative programmes and innovative concepts, the two ensembles have made a name for themselves for several years in the flourishing Swiss and European contemporary music scene. 

This collaboration begins with "Strata", the only Swiss work in the repertoire of this atypical quartet. Composed by Martin Jaggi in 2011, this acoustic piece is made up of different musical strata that are superimposed like a sedimentary slab. 

These four instruments form a unique combination with explosive potential, with colors that can be varied at will and with an almost seismic power. Continuing with this idea and updated with today's technical possibilities, the basic Instrumentarium is filled with an additional layer - electronics - which is developed within two large creations that complete the programme. 

The Belarusian composer Oxana Omelchuk is composing a new work that uses extracts of sound recordings from Strata as its basic musical material. Like an augmented remix, these deconstructed and reinvented sound objects - even to the point of becoming unrecognizable - enter into dialogue with the quartet's writing. To do so, the latter takes on another face: a viola and a saxophone filtered by effects pedals as well as a synthesizer and a drum set augmented by sensors.

Martin Jaggi composes a new piece that resonates with his first composition. Like a current look at his own music, this piece is like a malleable terrain where the different movements and reactions hint, at times, at the memory of his work Strata: a contemporary dive into the stratum of his own compositional style, ten years earlier. To achieve this complex challenge, Martin uses all the tools at his disposal, i.e. the entire Instrumentarium available, and cleverly plays with the acoustic and electronic mix.

Like the movement of tectonic plates, this encounter between these different worlds promises to be an exciting confrontation, with surging peaks, torn rifts and landslides as unexpected as they are exciting.
