I went to Vienna. It was and is a beautiful city, with much of its late 19th- and early 20th-century character still intact. And while there will always be other claimants to the honor, it's arguably still the classical-music center of the planet. I managed to score standing room for a performance of Puccini's Turandot at the Vienna State Opera (as I recall, standing room at the time was the equivalent of about $1 US). Act 1 was so rough that it evoked catcalls from the unforgiving Viennese audience, but after that, things settled in nicely.
