I'm always impressed by the power required for opera singers to project their voices out over the orchestra without microphones and music hall is always a great experience. Saturday's audience for Nixon in China was a nice mix of the usual opera crowd and some < 40's.
Slice of life is an interesting style for an opera. Most operas involve big dramatic events, murder, kidnapping, weddings, etc. This one kind of moved along and then was over. My favorite part was the pig song in the second act.
