Other composers have employed screaming in avant garde works in the twentieth century, typically in the post-World War II era, as composers began to explore more experimental compositional techniques and nonstandard use of musical instruments (including the voice). Composers who have used shouting or screaming in their works include Luciano Berio, George Crumb, Gyorgy Ligeti, Charles Mingus, Meredith Monk and Karlheinz Stockhausen. The use of hoarse vocals in choral and orchestral works continues today in some productions such as film scores; mainstream examples include some works by Don Davis and Wojciech Kilar.
