Mahalia Jackson. The Queen of Gospel. Born in New Orleans, raised in a shotgun house where music poured through every crack. Sang in church from age four, moved to Chicago at 16, and changed gospel music forever. Her voice was an instrument of such power and warmth it could make atheists reconsider. Sang 'How I Got Over' at the March on Washington just before Dr. King spoke. When she opened her mouth, she didn't just sing -- she testified.
