 Though the criticism of the work and the influence of Pierre Boulez as a composer is one of the main component of this essay, Duteurtre also put forward the problem of France's current nostalgia for its artistic leadership during the Belle Epoque in the late 19th-early 20th century.This idea will reappear later in some of these novels.In 1995, Marcel Landowski and Duteurtre created an association "Musique Nouvelle en Liberté" (New Music in Liberty) to promote new composers.
