Considered by many to be the greatest composer Canada has yet produced. Murdered at the age of 34, left behind 49 compositions in a variety of genres, including opera, orchestral works, and chamber pieces. In early 1970s, studied composition with Stockhausen in Cologne. A visit to Bali in 1976 proved pivotal, causing him to re-evaluate his ideas on the role of the artist in society. Visionary works that followed featured texts in an invented language, modal melodies harmonized by a complex overtone series, and shimmering orchestration. Called by György Ligeti “the greatest French composer of his generation”.
