Polytope XIa. An audiovisual exploration of Speicher XI A

Polytope XIa. An audiovisual exploration of Speicher XI A, inspired by Iannis Xenakis

Bremen (Germany), 19 – 21 April 2023

On the occasion of the 100th birthday of the composer, architect and multimedia artist Iannis Xenakis, students from several study programs at the University of the Arts Bremen have studied his /Polytope de Cluny/ (1972), an early milestone of immersive digital media art.
At the inauguration of Speicher XI A, a new university building for interdisciplinary dialogue in Bremen’s Überseestadt, they will now interpret the original audio tracks on a 3D loudspeaker setup and juxtapose them with a complex light production, developed specifically for this new space. Furthermore, new spatial audio compositions reacting to Xenakis’ ideas will be presented.

In the context of Meta-Xenakis, the international consortium created to celebrate Iannis Xenakis’s centenary, the Centre Iannis Xenakis (CIX), under the aegis of the GRHis research unit of the Université de Rouen Normandie, sponsored a research residency for Daniel Teige, internationally renowned audio-scenographer and uncontested specialist of the composer’s Polytopes. During this residency in Rouen, Teige created an exhaustive inventory of the bequest made to the CIX by Robert Dupuy (1945-2018), comprising the latter’s personal archives as one of the composer’s assistants and the main programmer of the first version of the Polytope de Cluny in 1972. During this process, all the items in the Dupuy Collection were also digitized for conservation and future reference.
It is this 122 page catalog which served as one of the original sources for a group of music, media and art students at the University of the Arts Bremen for their Polytope XIa, an homage to Xenakis and at the same time a special light and sound event for the inauguration of Speicher XI A, a new university building for interdisciplinary dialogue in Bremen’s Überseestadt. The project features a reinterpretation of the Cluny tracks on a 3D loudspeaker system and new spatial audio compositions reacting to Xenakis’ ideas.
