Everything that is ephemeral must be considered music. This also applies to live painting. Mathias Duhamel's art is based on the appearance and disappearance of matters, shapes and colors over time and not on their final organization on a canvas. The artist acts as a soloist painter who performs works of classical and contemporary composers according to his pictorial score. His own work evolves on stage by conforming to the temporal rules of music, rhythms and movements. When the music ends, the visual melody becomes silent at the same time. Only memory preserves the lived emotions.
