An encounter between a film artist with two 16mm projectors, and two improvising musicians ; a violinist and a guitarist. The will to propose a frictional dialogue between sounds and images, without a hierarchy between both medium : sounds can go with the images, as well causing them, incite them, confront them… images can initiate the mouvements, as well as melt into them. The will to experiment the fragility of a communication between loops on celluloid, expressing itself in a mechanical time, and the organic expression of wooden vibrant instruments.
