Allēlōn [/aˈli.lon/] :

ancient Greek, one-another, each other

This concept that is partially untranslatable embodies the notions of interdependence and reciprocity in exchange.

In 2021, continuing his ambition to develop a practice that bridges experimental improvisation and contemporary performance, Olivier Duverger Houpert began a Ph.D. in Musical Performance and Composition. After being diagnosed with bipolar disorder during his studies, his research took on a more personal dimension. Since then, he has sought to understand himself as a sum of multiplicities, each embodying different worlds and temperaments.

Based on his initial findings, four creators devised compositions to be improvised. With each performance, their musical encounter is reenacted, creating a space where Olivier allows himself to be shaped by otherness, all while searching for his own identity. The result is works in a state of perpetual becoming, oscillating between virtuosity and fragility, exaltation and poetry, control and surrender—neither quite the composers’ music, nor quite his own, nor simply the sum of their voices. In contrast to the identity-based isolation that poisons our societies, this mode of creation celebrates more mindful ways of encountering one another, of creating, and of being together.

The performance is presented as an exhibition to explore. Let yourself be guided by our introductory piece, a sound installation by Maïlys Trucat. Discover the space; let your ears and your imagination wander through our creative ecosystem.

​Allēlōn continues to expand within the collective with the piece Modular[0412-4:2].grch, composed by Mathias Berthod for the group Grch, which will have its preview at the Musica 2026 festival during the show’s premiere.
