This morning, Riccardo Muti led the Chicago Symphony Orchestra in music from an opera by Italian composer Pietro Mascagni who was twenty-seven years old when his work won a publisher’s prize as the best opera of 1890. We heard Muti and the CSO in one of the most attractive tunes from that opera: the ‘Intermezzo’ connecting the opera’s two scenes. What is the title of this opera by Mascagni?
