Presentation of the workshop online March 2025 (date to be determined)
Online discussions March—May 2025
Workshop during the Academy: Monday, June 16—Saturday, June 21, 2025 at the CENTQUATRE-PARIS

Object of the workshop

In 1972, Iannis Xenakis' Polytope de Cluny was a rare combination of sophisticated and popular art: an immersive sonic and visual experience, the prototype for many multimedia works. The spatialized soundtrack, the crackling flashes, the figures drawn by the laser beams and reflected by the mirrors... this unconventional work plunged the spectator into a hurricane of lights and electronic music.

In June 2022, the digital art studio ExperiensS and Pierre Carré (IRCAM) readapted the Polytope for the first time with its original monumental scale, alongside a new creation by the Italian collective /nu/thing with ExperiensS, Where You There at the Beginning. The new 2025 edition includes two new electronic creations, 665.99 (TremensS x Ténèbre) and CHLOÉ.

For the ManiFeste Academy, TremensS, Ténèbre, and Pierre Carré will be using the Polytope 2025 installation to explore the creative, experiential, and technical issues involved in an immersive audiovisual installation or performance.

Among the topics covered:

How can sound and visual creations be coordinated so that they work together to deliver a coherent multi-sensory experience, without competing or overshadowing one or the other? What technical strategies (hardware, software), particularly real-time and/or interactive for a live performance, enable this coordination and their simultaneous control?
How might we think in terms of ‘audiovisual instruments’ to go beyond the conventional logic of ‘visual illustration of a sound creation’ or ‘sound illustration of a visual creation’?
How can we standardise, invest, and spatialise the 3D volume of an immersive installation in terms of light and sound? How can the sound and visual references be aligned to ensure the coherence of the events perceived by the audience? How can an ‘invisible’ sound score be superimposed on physical and tangible visual/scenographic manifestations?
How can the spatial trajectories of audio and visual events be composed, designed, programmed and coordinated (workflow, software tools and protocols)?

Participants will be guided in the development of a spatialised musical work coordinated with a visual framework (LEDs, lasers) programmed by ExperiensS, which will be synchronised with the sound score (MIDI/OSC).

Warning: Polytopes has been identified as a potential seizure trigger (strobe or flashing lights) and is not recommended for peopel photosensitive epilepsy

The workshop is divided into several stages:

Between March and May 2025, the 6 selected candidates will receive support in preparing their project, through online meetings and email exchanges with the supervisory team
From Monday to Saturday, June —21, 162025, the 6 selected candidates will meet at the CENTQUATRE-PARIS to rehearse their works and attend master classes and practical work given by the supervisory team
On Saturday June 21, 2025 at CENTQUATRE-PARIS, their works will be performed in a concert as part of ManiFeste-2025

Remarques

Previous experience of audiovisual and/or immersive creation is a plus, but not compulsory. The workshop can be an exploration or a discovery of this discipline/exercise as well as a more in-depth study.
Familiarity with interactive multimedia creation tools (beyond pure audio) is a plus, but not compulsory. During the workshop, ExperiensS will be in charge of the visual aspect and the technical aspects of synchronisation with the audio. We want participants to be able to concentrate creatively, technically and calmly on the sound aspect, and they will be given technical support by the supervisors in interfacing with the lighting using simple, predefined bridges.
The main tools used, discussed or suggested during the workshop: Max/Spat, Ableton/M4L, Reaper, vvvv, Unreal Engine....
Candidates must be able to demonstrate that they have mastered Max and/or Ableton Live, so that they can use either tool independently (depending on their preference) for pure sound creation. They will be supervised on the other technical aspects (spatialization, bridge with lighting effects, etc.).

The Workshop is Led By

TremensS (Thomas Bouaziz) is an engineer and multidisciplinary artist who explores generative and real-time art in immersive technological installations with the aura of dark, futuristic altars, combining sound, light, image, and sculpture. He is the founder of ExperiensS, a design and engineering studio for digital and contemporary art, music and fashion, which is collaborating with IRCAM on the readaptation of Xenakis's Polytope in 2022.

Ténèbre (Paul Escande) is a sound designer and producer. Alongside his electronic projects (hybrid techno, bass music), he is lead sound designer for ExperiensS, creating the audio content for audiovisual and immersive installations in artistic, performance, and sound illustration contexts.

Together, they also form 665.99, an experimental/noise project based around generative, real-time music and immersive experiences, which is a new creation for Polytope 2025.

Pierre Carré is a graduate of the CNSMDP and holds a PhD in Mechanics and Acoustics from UPMC/IRCAM. His transdisciplinary artistic projects, combining sound and visual arts, explore themes at the intersection of the cultural, natural and technological spheres. Alongside his personal activities, Pierre Carré regularly works at IRCAM as a computer music producer. His musicological research into the work of Iannis Xenakis has led to the reconstitution of the Cluny Polytope with a view to its re-creation in 2022.
