Cantor David Wisnia, known to his family as “saba”, had never told the whole truth about how he survived as a prisoner at the Auschwitz Nazi concentration camp. The family knew that he had used his singing voice to entertain the guards, and that his musical gift had changed his fate. But David’s grandson, Avi Wisnia, suspected that there was more to the story. Moderated discussion to follow the film. RSVP here.
