#669 is a multidisciplinary project born in Amiens, France in 2016, from the encounter of Julia Berrocal and Marine Kloc. The first draw of the project was focusing on the relation between programming code and the body through sensors. Soon, the two artists tried to enhance the performance by improving the nature of the events triggered by the sensors. Aurore Leduc and Simon Leopold then joined the project to improve respectively the light design and the sound environment of #669. After two weeks of residence during the early 2017, the project kept its first aim : to create an interactive performance where the body is slowly led toward trance. But its sound and visual environment gained in depth and texture, delivering a dense, intense and hypnotic performance of 25 minutes where sound, space, light, body, shadow, dancer and public slowly melt altogether until a panting breath is the only thing left to hear.
