"Drawing is not simply a discrete part of the whole in Kentridge's art. It insinuates itself into the way he thinks and certainly into how he constructs images. Drawing is not a secondary medium to this artist. Talking with Kentridge, you get the sense that facing a sheet of paper with a graphite pencil or piece of charcoal in hand is not a preliminary activity but a primary one."
