In a 2018 video, William Kentridge says, “I describe myself as an artist living in Johannesburg, who makes drawings and sometimes the drawings are filmed and become animated films. Sometimes there are performers in front of the animated films and they become theatre or opera. So it becomes a drawing in four dimensions. In space and extending over time.” Simple. Yet Kentridge is not simple. He believes there’s “an important polemical and political role in art—in defending the uncertain.” Morality exists in his drawings, which tell stories of people under duress, dealing with injustice. This “Guest Piece” at Museo Picasso Málaga is a 40-foot-long eight-channel HD film installation. It show people walking, leaving one place to travel to another, carrying their belongings and their hopes. —Laura Jacobs
