"textural" compositions of the fifties and sixties such as Krzysztof Penderecki's Threnody to the Victims of Hiroshima (1959) and György Ligeti's works featuring micropolyphony in works like Atmosphères (1961) and his Requiem (1963–65). Other composers with works using this technique include Henryk Górecki, Karel Husa, Witold Lutosławski, Kazimierz Serocki, Steven Stucky, and George Crumb. Sound-mass techniques also appear in the music of Monic Cecconi-Botella and Harry Freedman.
