Gregor Leschig A person walks through a space. Another person observes him walking. The person walking through the space knows about his observation. Consciously or unconsciously he will decide for a certain presentation of himself – for a certain attitude, for a certain bearing. He asks himself: Which impression do I evoke? Which impression do I want to evoke? How do I convey the person which I think I am to the other individual. How do I convey the person which I want to be? The presentation of oneself onstage and the self-presentation in ones occupation or private life is my subject. Gregor Leschig - Stagings. bin-ich-arbeit.de is the website of his theatrical practice.
