FEATURE WRITING: Gene Weingarten of The Washington Post
Weingarten's "Pearls before Breakfast," according to the Post, "began as an audacious experiment in social science: What would happen if one of the greatest musicians in the world appeared incognito outside a Washington D.C. Metro station at rush hour and played some of the most beautiful music ever composed on one of the most valuable violins ever made?"
When readers learned that violinist Joshua Bell had played his Stradivarius "to an indifferent, unheeding audience," some said they were inspired to make fundamental changes in their lives. More than 40 clergy members crafted a sermon around the message they found in the story.
