Description: Groundbreaking singer, actor and activist Harry Belafonte rose to fame in the U.S. in spite of segregation, and crossed over into mainstream America on his way to international stardom. His hit 1956 album "Calypso" made him the first artist in industry history to sell over a million LPs, and spawned the smash single "Banana Boat (Day-O)." Though recognized with Grammy, Tony and Emmy awards, Belafonte was blacklisted, harassed by the House Un-American Activities Committee (HUAC), spied on by the CIA and FBI, and threatened by the Klan, state troopers and Las Vegas mafia bosses. Distilled from more than 700 hours of interviews, eyewitness accounts, movie clips, excerpts from FBI files, and news and rare archival film footage and stills, some of which has never been seen before, Sing Your Song reveals Belafonte as a tenacious hands-on activist who worked intimately with Dr. Martin Luther King, Jr., mobilized celebrities for social justice, participated in the struggle against apartheid in South Africa and took action to counter gang violence, prisons and the incarceration of youth.
