Interesting -- the country to the east is livecasting their big classical music festival (which would be well outside the budget for this peregrination, were I there).
I've been very miserly with my ticket purchases. The general theory has been good theatre and music for $5-$8 per night. I remember, also in the country to the east, perhaps my first stay there, there was a classical concert I very much wanted to hear -- the pianist had been a close friend of S. Richter, and she had come to prominence by winning the competition in the hall in which she was performing, and now returned to it at the end of her performing career. But it was just a bit over 20 Euros. I did make a point of noticing the hour when it happened, though -- I was staying less than a mile away, and I listened to a Richter performance.
Something to do with the meaningfulness of sacrifice, perhaps. Marking the time.
