I only found out about South African artist William Kentridge a short time ago (clutch hand to forehead and roll eyes) and then, only in the context of animation. Now I find out he is also a theatre and opera director. And I wish I could see his upcoming Metropolitan Opera production of Berg's "Lulu" at English National Opera. I will in some manner.
Meanwhile I start by sharing this short video from San Francisco Museum of Modern Art in which he explains and demonstrates his extraordinary animation technique based on making a drawing in charcoal.
