In the last few years, with their Orgue de bois (Wooden Organ), Denis Tricot and Eric Cordier have installed constructions which are at the same time sculpture and musical instrument in many public spaces. Each Wooden Organ is unique, conceived for the space that will receive it. A monument, a square, a street, a city... With it's long undulating wooden lines (successions of joined slats), it creates privileged spaces which are exposed to the public eye. After a performance, the audience is free to explore and discover the instrument's vast potential for musical sounds and noises. More that thirty Wooden Organs have been created in the lat four years in France and Italy. Generally around thirty metres long, these monumental yet extremely light sculptures integrate in their construction the basic principles of lutherie (instrument-building), and can be played like any string or percussion instrument. The Wooden Organ is very simply amplified. The recordings, like the concerts, use no electronic processing, but the monumental instrument.
