Note: This episode includes descriptions of childhood sexual assault. The drive for revenge can be all-consuming, especially when you or someone you love has been wronged. Outcast and distraught, the title character in Richard Strauss’s Elektra is obsessed with avenging the murder of her father. And because the story is based on a Greek myth, and Greek myths are full of dysfunctional families, this means that Elektra is hellbent on killing her own mother. We get our first taste of the darkness inside Elektra’s mind, and the trauma at the heart of her rage, in the monologue, “Allein! Weh, ganz allein.” It's a sort of primal scream accompanied by a huge orchestra, and Elektra plans her revenge in all its gory, graphic glory. Host Rhiannon Giddens and her guests explore the depths of trauma and the heights of vengeance, both for Elektra and for a man whose own drive for revenge brought him to those very same extremes of elation and despair. The Guests: Soprano Nina Stemme thinks there’s some truth to the story that Strauss once told an orchestra to play so loudly that they would drown out the soprano singing Elektra, and she should know -- she’s one of today’s leading interpreters of the role! She invested a lot of herself in shaping this character, and it's one that takes all of her physical and emotional energy to perform. William Berger is an author and radio commentator. Equal parts opera buff and metalhead, he brings his love of intense storytelling to his work at The Metropolitan Opera, and to his exploration of Elektra. While it's a story of violence and revenge, Berger thinks the real journey is the one of psychological discovery and deep Freudian conflicts bubbling to the surface.  David Holthouse is a writer and documentary filmmaker who spent three years of his life consumed by the desire for revenge. He meticulously plotted to murder the man who raped him when he was seven years old. He tells his story of childhood sexual assault in his first-person essay “Stalking the Bogeyman,” and follows up on his story in “Outing the Bogeyman.”
