@boneidol Uh! Old stuff which once was called Neue Musik (new music) in the 60/70s. More Names? Mauricio Kagel, Bruno Maderna, Luiciano Berio, Henry Pousseur and others I forgot. Stockhausen was always the poster child for that, but not the best. His composing methods were destructive, not creative. I even own a paper about his de-composition approach from him personally. Alas German only. One of his suns turned to a jazz musician.
