I'm reading a book and listening to "The Dharma at Big Sur" by John Adams. I had heard it on the radio and tried to buy it on Amazon; the cheapest option was £500 as I recall (so I didn't). About 3 months later it was on the free CD with the BBC Music Magazine - result!
No other piece of music divides me from my daughter more - she can't stand to be in hearing distance when I'm playing it.
