Renowned sound documentarian and audio-visual pioneer Tony Schwartz believes people should use tape recorders as much as cameras to capture meaningful events. Over the years he has recorded more than 30,000 sound portraits of New York City life, like the keeper at Central Park Zoo telling how he feeds lions, a Macy's elevator operator calling out floors and merchandise, children singing nursery rhymes, taxi drivers gabbing about their fares, musicians, politicians, and everyone in between, all without ever leaving his postal district.
