So farewell Pierre Henry, whose death was confirmed today aged 89.
A giant of contemporary music of the last 100 years, his ideas pushed the boundaries and tested the possibilities like few have done before or since.
It's facile to call him a pioneer of electronic music, there's much more to his work than just that, but it is true to say that his work blazed a trail for generations to follow. His intellectual weigh ensured that electronic music was taken seriously by the musical establishment, rather than just considered a novelty branch of cinematic sound effects which it could easily have been categorised under.
Henry saw the possibilities that were open to music in the 20th century and explored them with curiosity.
