In 1968 the choreographer George Balanchine made a ballet from two works by Xenakis Metastaseis and Pithoprakta and the following year he commissioned Xenakis to compose an original score for New York City Ballet. Antikhthon turned out to be one of the great might-have-been collaborations: Xenakis completed the score in 1971, but the work was never staged. The concept of Antikhthon Anti-Earth or Counter-Earth was first proposed by the Pythagorean philosopher Philolaus of Croton around 400 BC. He speculated that there was a Counter-Earth a hypothetical heavenly body that revolved with the earth around a Central Fire. This led to Philolaus being credited as one of the first to propose that the Earth was not the centre of the universe, but that it was in an orbit around the Sun (Central Fire), with the other planets.

These meetings are set to change the life and death of some of them.
