Allēlōn [/aˈli.lon/]:
one-another, one-another, from ancient Greek. This word, partially untranslatable, carries with it the notion of interdependence. It gave rise in French to the word allélopathie, designating the ability of plants to communicate through biochemical interactions.

​

In an ecosystem for creation, Olivier Duverger Houpert invites five composers each to propose a composition for improvisation, or comprovisation. The result is five independent installations, improvisation devices or improvised scores. The four performers-improvisers of Ensemble Grch and sound designer Maïlys Trucat explore meticulously written universes, redefining their contours through improvisation and enriching them with their own individual expressions. Between silence and eruptions, bruitism and modal evocations, immobility and micro-polyrhythm, Allēlōn is always, like its performers, evolving. Romain Gneouchev's staging and Lino Pourquié's lighting invite us to explore the space in search of our own intimate, personal listening to what's unfolding around us.

​

Allēlōn is crossed by the spectres of what weaves us, individually and collectively, to our multiple identities, to our environments, immediate and more distant, to our collective memories, our complexities. All that intertwines in our social relationships as well as in our relationships with others and with the here and now. Based on Olivier's research-creation work at the ACCRA research laboratory (University of Strasbourg), the program has been shaped since 2021 by regular exchanges and experimentation between all its protagonists.​

A proposal for new models for creation, a manifesto celebrating the vitality of improvisation and the writing of the moment, the circulation of knowledge and sensibility, openness to complexity and otherness.
