« Corps étrangers » is a collective project that gathers Swiss artists Vincent Barras and Jacques Demierre, Norwegian Caroline Bergvall, a French group called « l'encyclopédie de la parole » and scenographer Sylvie Kleiber. It consists in a multidimensional exploration of language. Its aim is to understand transversely the variety of oral forms. This is a show about voice, from lungs to lips, from meaningfulness to strangeness, a sound poetry arising from theatrical voice.
