When Ella Fitzgerald took the stage for the first time at the Apollo Theater in Harlem, “we heard a sound so perfect” that the entire theater went silent, says dancer and choreographer Norma Miller. “You could hear a rat piss on cotton.” Fitzgerald was 17 years old, and she had already faced severe racial discrimination. “Everything was race,” says Miller, describing the de facto segregation in Harlem in the 20s and 30s. “You couldn’t go out of your zone… slavery is over, but you don’t have jobs. So the confinement meant you had to do for yourself.”
