O explores the relationship of two walking bodies along an imaginary circumference. Perpetuated over time, this gait becomes a dance that investigates centripetal and centrifugal forces in which the two performers relate, intercept, follow and reject each other. The Idea of physics phenomena inspired not only the choreographic aspects of this work, but also the dramaturgy, stage and light design. The choreographic research works towards the activation of a specific panoramic body attention and peripheral vision, together with the experimentation of a sound system that integrates breath, steps, and voice of the performer. The piece insist on the relationship between the inner space of the individuals and a bigger spatial dimension, in a continuous negotiation between them and the rigid circle space they create step by step.
