Here is something to read about the latest incident of booing at La Scala, this time for Cecilia Bartoli. Unlike Alagna, she does not seem to have stormed out. We rely on Italy for opera rioting. There seems to have been an issue with the ticket prices.
P.S. It is now my understanding that this has to do with paying off the claque.
