In an ideal world I would be writing novels about groups of revolutionary anarchists smashing society before rebuilding it based on fairness, equality and respect for all living creatures.
So for the first violent part of the book RATM - Killing In The Name Of would be perfect. So would The Animals - We Got To Get Out Of This Place in a different way.
I would definitely get Henry Rollins on the soundtrack, either his solo work or as part of Black Flag. Rise Above **has** to be there now I think about it. Basically anything conveying righteous anger, rage and fury so thrash metal, hard core punk, techno, jungle, old skool gangsta rap, drill etc.
Of course there cannot be just "western" music on the soundtrack. It needs music from all around the world as the revolution in the book would be global.
After the revolution takes place am not so sure about the music. I don't want it to be what my mother would call "All hippified" Peter Gabriel - Solsbury Hill or the Kinks - Waterloo Sunset have the right tone but they are still a little hippified in my book. I am not sure if the sort of music that I am thinking about even exists. Probably listening to more music from around the world would be a good place to look for it.
