Bernd Alois Zimmermann (March 20, 1918 - August 10, 1970 ; full name "Bernhard Alois Zimmermann") was a post-WWII West German composer. He is perhaps best known for his opera Die Soldaten which is regarded as one of the most important operas of the 20th century. As a result of his individual style, it is hard to label his music as avant-garde, serial or postmodern. His music employs a wide range of materials including the twelve-tone row and musical quotation. Wikipedia
