The Upgrade! Paris #10

Upgrade! #10: Cyrille Henri and Nicolas Montgermont present chdh
Date: Friday, the 15th of June 2007 at 7:00 PM
Place: Point Ephémère, 200 quai de Valmy 75010 Paris, M° 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

Cyrille Henry, artist and multi-field developer, he is interested in
interactions between human gesture and data processing for artistic
exploration. He’s 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 Lumières, 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 Nçio, a minimalist and
numerical sound.
