Hans Werner Henze died at the age of 86 in 2012.  He was a German Atonal Composer and left Germany for Italy in 1953 due to an intolerance toward his left wing politics and homosexuality.  He became a member of the Italian communist party and indeed wrote a Requiem in 1968 for Che Guevara and Ho Chi Minh.  He even spent a year teaching in Cuba.  Whilst his father enrolled him in the Hitler Youth, it was clear that music was his forte and after the Second World War he became a Conductor at the Wiesbaden Staatstheater.
