Sidney Leoni (FR) develops works that draw attention on notions of sensation, affect and on a participatory relation with an audience. In 2010, he created in collaboration with several guest artists the project Undertone that proposes an immersive experience of several kinds of stimuli: tastes, sounds, smells, temperature fluctuations, touches in complete darkness. In 2008/09, he took part of the Master Program Research In Choreography with Mårten Spångberg at the University college of Dance in Stockholm and in 2004/06 as part of the Master Program Research in Dance at the University Sophia Antipolis in Nice.

Sidney performed in the piece Giant City (2009) by Mette Ingvartsen, The Host (2010) by Andros Zins-Browne and collaborated with Mychoreography (Sweden - 2008-10). He is currently involved in a new collaborative project with Luís Miguel Félix entitled War of Fictions which premieres in September 2011.
