ChDH Collective

ChDH Collective

The chdh collective studies image/sound relationships by creating visual and audio algorithmic synthesizers. They mainly use these audiovisual instruments in live performances. Using equations that describe natural mechanisms, they generate abstract choreographies of particles whose minimalist matter reveals underlying structures of great complexity, formed by strange organic attractors. In search of a synesthetic radicality, his hypnotic performances work on joint movements between image and sound and belong as much to experimental cinema as to improvised music in the way they are performed.

Since the early 2000s, they have shown their projects on more than a hundred international stages, most notably the presentation Egregore (2011), which explores the group movements of a multitude of particles, and Morphist (2015), a study of the transitions of form of an abstract substance.

This work has also led to two editions: the DVD Vivarium (Art Kill Art/Arcadi – 2008) containing abstract works on video, as well as the software developed for these creations, which proposes to “play” or edit them, and the Egregore Llave font. USB (Art Kill Art – 2014), an adaptation of the software used for Egregore, which has resulted in remote performance on more than 120 computers in some twenty countries.

Defender of free software, he freely distributes his projects and the tools developed for his work, including the pmd physical modeling library for Pure Data.

Cyrille Henry, an artist and developer in multiple fields, is interested in the interactions between human gestures and data processing for artistic exploration. His work was directed towards sensors or physical modeling for gesture analysis, human interface devices, and real-time sound and visual synthesis. He worked 4 years at La kitchen in Paris (in charge of the hardware department) for the development of sensor interfaces and their uses in an artistic context (live performance, dance, interactive installation, music). He is one of the founding members of the chdh project. Since 2005, he has been working as a freelance developer/engineer in the field of pure/Gem data and sensors.

Nicolas Montgermont explores the physicality of waves in different ways. He is interested in the reality of waves in space, the way they move and change, the links between a source and our perception, designing configurations that create a sensitive exploration of his poetic essence. He works with sound waves mainly through the vibration of materials and their propagation, natural and artificial electromagnetic waves in the form of radio landscapes, gravitational and sidereal energies through the astronomy/astrology double prism.

He creates installations, often in collaboration with Cécile Beau and formerly in the Art of Failure collective, in which time is of particular importance and allows for an intimate appropriation of these materials and energy, he is also active in the field of audiovisual performance with chdh and in experimental music with BCK and Yi King Operators. He has published several editions in Art Kill Art. His projects are shown in many centers in Europe and elsewhere (Club Transmediale, Elektra, MusikProtokoll, Fondation Vasarely, Palais de Tokyo, WRO, iMAL, PixelACHE, …).
