Serial music remains, over 50 years after its founding, enormously controversial, attracting both ardent defenders and vehement attacks. Philip Glass described the School of Paris as "crazy creepy people writing crazy creepy music", while on the other hand one critic said that Boulez' Sonatas "reveal a sparkling world of turbulent passion and abstract beauty. " Many composers, such as Rochberg, who had been ardent serialists have largely abandoned the style, while many younger composers have never been attracted to it. Various terms have been introduced to describe this trend away from Serialism, such as the New Romanticism, etc. See: minimalist music
