Airs Saturday, July 25, at 12 noon. This week from the LA Opera it's a double bill featuring two seemingly disconnected works, Dido and Aeneas By Henry Purcell And Bluebeard’s Castle By Béla Bartók. The common thread? Tune in and find out. Steven Sloan will lead the LA Opera Orchestra and Chorus in Dido and Aeneas staring Paula Murrihy as Dido and Liam Bonner as Aeneas, with Kateryna Kasper as Belinda, John Holiday as the Sorceress, Summer Hassen as Second Lady, G. Thomas Allen as First Witch and Darryl Taylor as Second Witch. Our cast for Bluebeards Castle will feature Robert Hayward as Bluebeard and Claudia Mahnke as Judith. Duff Murphy will host.
