This just in from a conductor who’s watching the live stream on a screen a few hundred metres from the theatre:
Diana Damrau missed her entrance in Act II, party scene in Traviata. The orchestra went on without singing and almost stopped for a really long embrarassing time. This is at La Scala Opening night, with Traviata, conducting, live streaming worldwide. Apparently, she just did not reach the stage on time. Daniele Gatti, conducting, will want to know why.
UPDATE: Despite the lapse, Damrau was greatly applauded at the end. Our observer writes: She has sung a very convincing performance, the incident should tell more about the stage personnel at La Scala than about her. Both the conductor and producer were booed.
