When we think of opera's biggest stars and greatest hits, we tend to think of solo arias. But that overlooks another operatic goldmine: duets.
Over the years, there have been plenty of classic duet collaborations, resulting in legendary recordings and performances. Mirella Freni and Luciano Pavarotti come to mind, singing the "Cherry Duet" from Mascagni's L'Amico Fritz. Going back a little further, there's Jussi Bjorling and Robert Merrill with "Au fond du temple saint," the famous duet from Bizet's The Pearl Fishers.
