Local theater staff was very helpful and offered refund or later viewing of most disturbing sound and picture difficulties. Though intermittent, the tension of wondering when it would interrupt again or worse, lessened our enjoyment. The singers were wonderful and of course the staging was impressive. I must admit the first act's pomp and plumage along with the sheer numbers of folks on stage (though nearly hidden in the generally dark and mysterious setting) almost overshadowed the music. I loved it, but think I love a little less glitz and glamour. I recommend going, and look forward to another opera, this time with no tech problems.
