Hi Christy,
I feel booing is a good response to have. Why only have
standing ovations?
I also find booing in a concert very much part of civil discourse, as long as it's not during the performance (
post) but only after it. How else would the discourse go. People nowadays want to have their say, and I don't think it is fair to tell them: clap your hands in appreciation and yell bravo, or Shut up. If you accept clapping, booing is just as much part of the discourse.
In fact, in England they have the habit of the entire crowd hissing when a villain comes on stage in the theater. It's a strange habit, but also nice, and part of crowd participation.
I haven't seen Luc Bondy's production of
Tosca, so I can't comment on it specifically. Perhaps one one can see the booing as part of the performance? And really, some of these interpretations are so bad I wish I could boo too every once in a while.
