What does redemption mean to a man sentenced to death? Is capital punishment justice or vengeance? Could anyone ever forgive a murderer?These are just some of the questions behind the true story of the nun who became a spiritual adviser to men on death row at the Louisiana State Penitentiary. Dead Man Walking was first a 1993 memoir by the Catholic nun and fervent death penalty abolitionist Sister Helen Prejean; later, it was adapted into an Oscar-winning movie. Sister Helen’s story inspired a national conversation around the death penalty — and the opera duo Jake Heggie and Terrence McNally. Their adaptation of Sister Helen’s story has become one of the most celebrated operas of the 21st century, and, with the last federal execution taking place as recently as 2021, feels as timely as ever.In her aria “This Journey,” Sister Helen’s character reflects on her religious calling as she makes her way to the Angola prison for the first time. In this episode, host Rhiannon Giddens and her guests take us deeper into the true story that inspired the opera and the experiences that continue to inform Sister Helen Prejean’s ministry.The GuestsThe Metropolitan Opera’s 2023 production of Dead Man Walking marks the fifth time mezzo-soprano Joyce DiDonato has sung the role of Sister Helen. She describes the role as one that’s impossible to emerge from without feeling changed. Having embodied Sister Helen so many times, DiDonato feels “much less comfortable turning a blind eye to things.”American composer Jake Heggie is best known for Dead Man Walking, the most widely performed new opera of the last 20 years. In addition to 10 other full-length operas and numerous one-acts, Heggie has composed more than 300 art songs, as well as concerti, chamber music, choral, and orchestral works. When librettist Terrence McNally proposed adapting Dead Man Walking into an opera, Heggie’s “hair stood on end” and he immediately “felt and heard music.”Sister Helen Prejean is a Roman Catholic nun, the author of the memoir Dead Man Walking, and a leading voice in the effort to abolish the death penalty. She’s served as a spiritual counselor to numerous convicted inmates on Death Row as well as to families of murder victims and survivors of violent crimes. Despite her wisdom, Sister Helen claims to know “boo-scat” about opera.
