During the 1800s, the ethnically diverse inhabitants of Malaga—a small island off the coast of Maine—lived together in harmony. Suddenly, in 1912, the state governor ordered the forcible removal of all the island’s inhabitants. They were taken to the mainland, where no jobs, housing, or support were on offer. Responding to this forgotten moment in history, Theaster Gates has created “Amalgam,” a convergence of sculpture, installation, film, and dance (by choreographer Kyle Abraham) that speaks to the island and its stolen people. —E.C.
