Apartheid. War. Colonialism. These are core subjects for William Kentridge, the multifaceted South African artist. Kentridge is known for the political films he makes out of drawings in charcoal (he photographs a drawing; partially erases, redraws it, and photographs it again; eventually these successive images add up to a movie). He also creates fascinating sculptures and triptychs, using recurring symbols that are the basis of a Kentridgean lexicon. This exhibition in New York City presents his film series “Self-Portrait as a Coffee Pot,” as well as the 70 works on paper that went into its creation. The show spans both floors of the gallery’s 22nd Street location and expands into its 18th Street gallery too. —Elena Clavarino
