If you want to attend a La Scala performance on Friday come to Vienna. And don't be confused if you see the Vienna State Opera on stage in Milan on the same day.
It is the first time the two houses are simultaneously switching venues.
A Vienna opera statement Wednesday said Daniel Barenboim will conduct Verdi's Requiem in Milan with Violeta Urmana, Daniela Barcellona, Rolando Villazon und Alexander Vinogradov.
At the same time Franz Welser-Moest will conduct a concert version of Beethoven's "Fidelio." Soloists are Nina Stemme, Peter Seiffert, Markus Marquardt, Albert Dohmen, Hans-Peter Koenig, Anita Hartig and Norbert Ernst.
