“Most young kings get their heads cut off,” Jean-Michel Basquiat once said. Not only was he a young king, but he stamped yellow crowns all over his paintings. Basquiat was also obsessed with heads. He drew them constantly, in oil stick on paper, often disembodied, stripped of his usual symbols and text. The faces—stylized, slightly alien, with eyes and mouths that seem to open onto another world—weren’t preparatory sketches. He kept them mostly for himself. The Louisiana is now presenting a major show of these drawings. It’s the first to look at Basquiat’s fixation on the human head. —Elena Clavarino
