Why was this play performed in front of a black-only audience?

Black performers and producers across the US are increasingly hosting special screenings of their work for exclusively African-American audiences. Many are following the footsteps of playwright Jeremy Harris who earlier reserved all the seats for his show "Slave Play" to black students, journalists and performers. "Choir Boy" director Maurice Parent gathered black-identified artists, activists, intellectuals, creatives, and students to watch the play.
