Whenever Opera Chic reads something like celebrity opera singers complaining about "punishing schedules", or musicians ranting about jet-lag, she thinks of poor old maestro Gino Marinuzzi: in his letters, Opera Chic's favorite book like ev4r, he lamentates the VERY punishing schedule of a South American tour with, like, 7 performances a week, 8 sometimes, of two or three different operas.
Then, Opera Chic has found this amazing site by Professor Hans Pizka with all the info on the Wiener Philharmoniker's South American tours in 1922 and in 1923.
The good Professor's homepage is here.
