Whitney Houston [SEP] 1963–1984: Early life, family, and career beginnings
Houston was raised a Baptist, but was also exposed to the Pentecostal church. After the 1967 Newark riots, the family moved to a middle-class area in East Orange, New Jersey, when she was four. Her parents later divorced. At age 11, Houston started performing as a soloist in the junior gospel choir at the New Hope Baptist Church in Newark, where she also learned to play the piano. Her first solo performance in the church was "Guide Me, O Thou Great Jehovah". While Houston was still in school, her mother, Cissy, continued to teach her how to sing. Cissy was a member of the group The Sweet Inspirations which also opened for and sang backup for Elvis Presley.
