There's a fascinating story in the Washington Post (Pearls Before Breakfast) about an experiment where a leading young violinist plays solo in a Washington train station during rush hour: who will stop? who will give him money? who will even notice?
This is a well-written piece with lots of aspects: a story about the musician, about the music, about commuters, workers and those who actually stop. How many people stop? How much does he collect? What does it say about our lives? Worth reading.
