Pneuma - Wärmezeitmaschine is an immersive, participatory performance that places breath at its centre - as a primal force of life, a collective bond, and a political symbol. The performer inhabits a resonating space in which his breath is acoustically amplified. Visitors are invited to become part of this sonic fabric through their own breathing. In this way, a living interplay of sounds, rhythms, resonances and bodies emerges - an acoustic sculpture, a breathing collective. Pneuma means both "breath" and "soul" in Greek. The performance reflects on breath as a carrier of identity, a communicative potential, and a mirror of the macrocosm. Breath is as essential to our life as it is fragile - it can be hindered or suppressed, as demonstrated by pandemics or methods of violence and oppression. Inspired by Joseph Beuys' participatory art concepts and his energy plan as well as by the breathing practices of the Marina Abramović Method, the project sees itself as an artistic-social experiment, a sensual and political invitation to attend to breath as a "primordial sound", the most reduced form of togetherness, and the most elemental form of relating to the world.
