The American soprano Nadine Sierra's second album for DG, 'Made for Opera', focuses on three timeless operatic heroines, Verdi's Violetta in La traviata, Donizetti's Lucia di Lammermoor and Gounod's Juliette from Roméo et Juliette. She's partnered by the Orchestra Sinfonica Nazionale della RAI conducted by Riccardo Frizza. Gramophone Podcasts are given in association with Wigmore Hall. James Jolly caught up with Nadine Sierra by Zoom to talk about the album and her relationship with these three remarkable operatic women.
