"Chamber Rites is an encounter based on sharing emotions, on audio-visual exchange, on the practice of radical improvisation, characterized by a location or context, of which we define a part of its mobile architecture. Ours is a ritual whose coordinates -- spatial, temporal and performative -- are traced by signs, at the same time enigmatic and visible, sedimented in time" --Fabrizio Casti and Elio Martusciello, 2015.
