Two hundred of the world’s most important galleries of modern and contemporary art reunite on Miami Beach’s hot shores for “one of the most dynamic, diverse art events in the country,” as the New York Times describes it. Gagosian, Hauser & Wirth, Simon Lee, and many more are setting up shop. Expect an endless array of paintings, sculptures, installations, video and digital art by 4000 leading artists, as well as endless talk about aesthetics well into the evenings, after the Convention Center shuts its doors. —E.C.
