Making a concert means work. ›SKILLS‹ alias Camilla M. Fehér and Sylvi Kretzschmar investigate links between the body, technique, control and chaos in a concert performance that appears to be the acoustic result of perfectly synchronized hand grasps, sweat-inducing motion and piles of self-soldered cables. There is no way to distinguish whether the body reacts to the music or the music is initiated, produced and modulated by the body.
