The Pearl Fishers
From the Lyric Opera of Chicago website:
For sheer transcendent beauty, Bizet’s The Pearl Fishers has few rivals in the entire repertoire. The opera’s famed duet for tenor and baritone is a soaring melody that has turned countless opera newcomers into ecstatic fans. Bizet (who composed this work 12 years before Carmen) transports us to Ceylon, where two devoted friends find themselves in love with the same woman, an entrancingly beautiful priestess, Leïla. From its leading men and leading lady, The Pearl Fishers demands the ultimate in vocal beauty and elegance to do justice to this sweepingly romantic drama.
