Making this film was pure serendipity. After a January snowstorm in New York City, I decided to do some work on another film, in my home in Washington Heights. But as I approached my desk, I thought I heard a piano plinking. I looked out the window and saw a piano on the curb below. I was mesmerized by the pattern that emerged. Passers-by would slow, stop and play. Some played well. All day long they collected and dispersed, and into the night they measured, shoved and deliberated the piano’s fate. (If it stayed on the sidewalk, the city could have issued a fine.) I was riveted. Pianos have histories. No one who stopped seemed eager to leave it behind. Their thoughts were obvious: Can we take it? Who abandons a piano? Is it worth anything?
