I'm planning a unit on 'Protest Music' for my Year 10s next year (IB curriculum, so no GCSE restraints). Last year I focused just on 20thC popular protest songs, but I'd like to diversify a little next year. Can anyone suggest some pieces of 'classical' music that were written in 'protest'? Eg. Shostkovich's 7th Symphony, protest against the tragedies of WWII: "I had to write about it, I felt that it was my responsibility, my duty. I had to write a requiem for all those who died, who had suffered ... I had to describe the horrible extermination machine and express protest against it."
