The concept of chance utilized by John Cage is a frightening, exciting, and liberating process for any artist. It was so effective that other musical artists such as Morton Feldman, Earle Brown and Christian Wolff used it. In the world of theatre these concepts are constantly used today by the Neo-Futurists in Chicago and New York in their production of Too Much Light Makes The Baby Go Blind and by Improv Troupes throughout the country.
