You go to the home of Strauss, Beethoven, Mozart, and Haydn, and so you naturally want to hear some of their music there. That was good.
However, what was most mind-boggling for me (and my son) was the Breughel collection at the Kunst Historische Museum:
It was a long, jet-lagged and befuddled but scenic trek to get there on our first day after a sleepless plane ride, but our Breughel mission was worth it to get close to those pictures. They have a third of the existing Breughels. They are quite large paintings with many small details, and no reproductions can do them justice. Some are oil on board, and some are tempera. You have to go and see with your own eyes. They have comfy leather sofas to sit on, too.
Pictures tell stories. If they don't, they are just "design." That's my opinion, anyway. People sure do love stories, especially when well-designed. I do not mean to disparage design: Picasso was a master of design. Matisse too, and the genius cave painters of Lascaux.
Hunters in the Snow (1565), his haunting hunting masterpiece:
Peasant Wedding, another masterpiece:
A good summary of Breughel's career here. It's interesting to me that the wealthy churchmen and princes of Austria found this Flemish painter's work so collectible. I guess they just had good taste in art.
