One of the most influential artists of the 20th century, Mark Rothko’s signature style helped define Abstract Expressionism. After a screening of the new American Masters documentary, Rothko: Pictures Must Be Miraculous at the Museum of Modern Art in New York, Rothko’s daughter and son, Kate Rothko Prizel and Christopher Rothko, sat down with series executive producer Michael Kantor and director Eric Slade to discuss their father’s legacy. This is a bonus episode of the American Masters Podcast.
