Bohuslav Martinu

Desire versus reality on this week’s Sunday Opera (3/15 3:00 p.m.) as we look to a 1938 work by Bohuslav Martinu that was based on a French surrealist play by Georges Neveux entitled “Juliette, or the Key of Dreams.” “Julietta” is the object of desire of a travelling bookseller, and he travels to the world of dreams to find her, even though he’s never seen her. He’s just heard her singing.
