Racism in opera - the story of Emmanuel "Onry" Henreid
Black opera singer Emmanuel "Onry" Henreid went viral in June with a video of an impromptu duet with a student Madisen Hallberg performing national anthem - a moment of racial unity during the Black Lives Matter protests. BBC talked to Onry - he described how he was told he wasn't able, physically, to sing opera, and how he is prevented from singing by the police anywhere outside opera houses.
