Opera can be embarrassing. The music is wonderful, the poetry is 19th Century sentimentality. How can you listen to lines like "Oh sweet kisses, oh languid caresses and I, quivering, unveiled those beautiful shapes!!!" without wincing?
Placido Domingo, in a recent Great Performances production, talked about singing Tosca. Why he loved it. It's the emotion, he said. Lines like "languid caresses" bother him not at all. He gets it. He gets into it. Listen!
