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.
Movement as a mean of expression

The chdh project is based on two laptop computers connected by an Ethernet connection on which musician control information flows. In order to allow representation of fast and complex movement, the images synthesis is fast and accurate. The software environment used is the Pure Data which is the principal source of inspiration and exploration.
All the software used and developments made by chdh have an open sources licence allowing the free use and distribution.

Following the creation of an independent produced album of electronic music improvisation “Chaos & Dharma” in 2002, chdh focuses around the relations between images and the sound. From 2003 until today, chdh presented its work in many Parisian places (IRCAM resoffnances - Les Voutes - Confluences - Mains d’Oeuvres - Résonaces_aux) and on festivals abroad (Pure Data convention in Graz (AT), the P1k53l free software festival of Bergen (NW), the PixelACHE festival of Helsinki (FI) and the 23 Kassel DokFest (DE). In 2004, the collective carries out a creation residence in the “Confluences” arts centre leading to a sound & video installation: cinéradian, and to a series of workshops.
