Upgrade! Paris



Upgrade! Paris: Cyrille Henri and Nicolas Montgermont present chdh :: Date: June 15, 2007 at 7:00 PM :: Place: Point Ephimhre, 200 quai de Valmy 75010 Paris, M0 Stalingrad :: Mediator : Dominique Moulon.

chdh is a live hybrid performance, offering a symbiosis between the sound and the image. Between minimalism and industrial, chdh creates a single, cold but organic universe. Thanks to the use of mathematical algorithms and physical models, chdh brings a new vision of the use of data-processing tools in musical creation. The use of audio-visual objects, having a sound component and a video component controlled by the same parameters allow an effective management of the relations between the two medias.

This project evokes a virtual world, made up with more or less autonomous abstract creatures. The aesthetics of the video and the sound is minimalist: sines, diracs and noises interact with cubes, spheres and other primitive in 3D on a black and white visual environment.


The role of chdh during live performances is to play with the movement of these objects, in order to make them live and react. Two musicians handle the instruments by using an abstracted layer, software representation of the audio-visual object. Each algorithm then creates data used for the video synthesis and for the sound synthesis, creating a strong cohesion during the performance.

Cyrille Henry, artist and multi-field developer, he is interested in interactions between human gesture and data processing for artistic exploration. His work was directed in turn towards the sensors or physical modelling for gestur analysis, human interface devices, as well as the sound and visual synthesis in real time. He worked 4 years in La kitchen in Paris (in charge of the hardware department) for the development of sensors interfaces and their uses in an artistic context (live spectacle, dance, interactive installation, music). He is one of the founder members of the chdh project. Since 2005, he works as a free-lance developer/engineer around pure-data/Gem and sensors.

Nicolas Montgermont, researcher and artist, studies the relations between art and sciences using the computer as a workshop. After a formation in signal processing, he studies sciences applied to music at the IRCAM center, being specially focused on real time control of synthesis. Currently, he carries out a PhD thesis on the analysis of the flutist playing at the Laboratory of Musical Acoustics (LAM) in Paris. His creating work is the search of a numerical aesthetics, using and developing personal tools to explore the specific possibilities of a computer. Founder of Basses Lumihres, an association working on the fusion of the relationship between various mediums of the contemporary art, he works mainly in the musical field, through three projects : chdh ; ABM, a break/noise laptop duo and Ngio, a minimalist and numerical sound.
