Airs Saturday, December 7 at 12 noon. The 2013-14 Metropolitan Opera Radio Broadcast season begins with a live broadcast of Verdi’s Rigoletto, starring baritone Dmitri Hvorostovsky in his first company performances of the title role. Tenor Matthew Polenzani co-stars as the Duke, and two artists make their network broadcast debuts: Bulgarian soprano Sonya Yoncheva, who sings Gilda, and Spanish conductor Pablo Heras-Casado. Bass Štefan Kocán and mezzo-soprano Oksana Volkova reprise their roles as the corrupt siblings Sparafucile and Maddalena, which they sang last season in the premiere of Michael Mayer’s acclaimed production. Rigoletto will be heard live over the Toll Brothers-Metropolitan Opera International Radio Network at 12:00 p.m. CT on Saturday, December 7.
