With a career spanning over 40 years, Mahalia Jackson rose to international stardom, rightfully earning the title of "Queen of Gospel." Her vast discography and powerhouse performances made her the voice of the civil rights movement, inspiring iconic activists and singers for generations -- from Martin Luther King, Jr. to Aretha Franklin -- and she hoped that her music and singing for racially integrated audiences would encourage racial equality and real change. GRAMMY(R) Award-winning singer-actress Danielle Brooks gives a stunning portrayal of this legendary artist in ROBIN ROBERTS PRESENTS: MAHALIA.
