Horatiu Radulescu has died.
This email from pianist Ian Pace to the academic mailing list Music-Since-1900 is where I heard the news:
I just heard last night the very sad news that Horatiu Radulescu has died. He had been seriously ill for several months. A fantastic composer of passionate, hallucinatory music, and of vital importance in the history of spectral music. May he rest in peace.
Radulescu’s Wikipedia page has been updated stating that he died in Paris on 25th September.
Update (29 Sept 2008): obituaries are still few and far between, but some have started to come in:
Resmusica (Bruno Serrou)
Rue 89 (Nathalie Kraft)
