Seeking Sound Underground: A Tool For Music (VIDEO)

Moses Josiah plays the guitar. From time to time, he plays the piano. But his favorite instrument is a little less commonplace.

Josiah, 80, is one of a small crowd of musical saw players in New York.

Every July saw musicians from across the world come to New York to play together. Last summer, 53 musicians played together in Astoria and Brooklyn.

"Thank Heavens, we got in the Guiness Book of World Records," he said.

Josiah started playing in Guyana, where he was born. He has played on television and before Queen Elizabeth II. He's also the subject of a documentary that's set to be released in May.

Today, a retired orthopedic technician, Josiah plays at Union Square, Times Square, Grand Central and Atlantic Avenue. For him, it's not really a way to make money. It's mostly a way to keep busy.

"I do this to keep my mind intact," he said, laughing. "You know?"

When he's not in the subway, Moses Josiah plays concerts, banquets and weddings. He can be reached at
