The choreographer George Balanchine and the art patron Lincoln Kirstein established in 1934 the first school of ballet in the United States, a bastion of modern dance, followed by the group which received in 1948 the official name - New York City Ballet. As part of the group, Balanchine created several of his iconic abstract ballets, such as "Four merge". along with American works, in terms of movement, music and content, such as "Who Cares?".
