Belgian modern composer Henri Pousseur has written well over 100 works in a variety of styles, and has served as a music educator for several decades. By the time he was finished with his music studies in the early '50s, Pousseur was already active in avant-garde music, influenced by and creating music not unlike that of Stockhausen and Berio. Pousseur's works included serial music, experimental operas like "Electre" (1961), and electronic music such as "Scambi" (1957). He began his longstanding collaboration with Michel Butor in the early '60s; the duo have gone on to write over 20 works, including "La Rose Des Voix" (1982). Pousseur founded the Centre de recherches et de formation musicales de Wallonie in Liège, the magazine Marsyas, and taught in several countries (but mostly at the University and Conservatory of Liège) until his retirement in 1994. ~ Joslyn Layne, All Music Guide
