Arguably the greatest choreographer who ever lived, George Balanchine was one of the cultural titans of the twentieth century. His radical approach to choreography—and life—reinvented the art of ballet and made him a legend. Written with enormous style and artistry, and based on more than one hundred interviews and research in archives across Russia, Europe, and the Americas, Mr. B carries us through Balanchine’s tumultuous and high-pitched life story and into the making of his extraordinary dances.
