Music performer and visual artist, Pietro Pirelli combines innovatively sound, vision and space. He explores the dimensions of stone, water, light and turns the physical phenomena into interactive performances-installations, to change the percepion of the space where they are staged. The location itself is transformed in an artwork to be visited. His most famed are Arpa di Luce (with Gianpietro Grossi), Idrofoni, the Vertical Circular concept installation and Suono Liberato, an exploration in the sound universe of stones. Among locations in Italy: Biennale of Venice, MAGA museum Gallarate, Fondazione Sandretto Re Rebaudengo and Rivoli in Turin, MACRO Rome, Villa Panza Biumo. In Milan: Triennale, Castello sforzesco and Palazzo Reale and Piccolo Teatro. Founder of AGON, Milan, he took part at many events staged by this institution. In may 2005 he opened the Ravenna Festival with his Mirabil Uso. In the world he performed at The Living Theatre NY, Light Kone Paris, Mam Sau Paulo Brasil, Luminale Frankfurt. Nazareth, Palestine. He realized the street-art project Mumbay Traffic Flowers in India and with his Artificiale Naturale he staged a live installation in Haeinsa Temple in South Korea.
