John Cage: 49 Waltzes For The 5 Boroughs

John Cage's artwork, “49 Waltzes for the Five Boroughs”, appeared in the October 6, 1977 Rolling Stone magazine – a gala issue celebrating their move to New York. He constructed his “waltzes” through chance operations as a series of 49 multi-colored triangles superimposed on the Hagstrom map of New York City.
