The lead tenor, Victor Campos Leal, sang the role of Alfredo in Verdi's Traviata splendidly and is surely headed for a big career! I met him on a train dining car from Frankfurt (Oder) to Berlin, and he was flying to Vienna for a voice lesson. He invited me to hear him sing to hear the result.
Good thing I took the train to the right city -- I had no idea that Breslau = Wrocław. I kept trying to buy a ticket to "rock-law" and the German ticket seller told me I wanted to go to Breslau. I was so confused. Before the end of WWII, Wrocław was part of Germany and called Breslau.
