Stock Market Put to Music

A couple of years ago I read in a book called “The Best, the Worst, and the Most Unusual”, about a musician who somehow translated the weekly Stock Exchange, Stock Market, Nasdaq, or some economic indicator of the sort, into classical music, each number representing a different key on the scale.

I was hoping to research this musician, whoever he was, in more depth, but unfortunately I no longer have access to that book, and I can’t remember what the artist’s name was.

So, I was hoping someone here would know who that wacky guy was? Any more information on the web about him or his music?

Thanks in advance!

Sounds like the sort of thing John Cage would do.
