i doest have to neccessarily be instrumental. but the song needs to be happy in the beginning then build up to being all angry and violent. if this makes sense to anyone please help me. Deftones ~ Change
It's not instrumental, but it's the only song I know of that suits this topic. You might find some good stuff on the soundtrack for the movie "go". It has a lot of cool instrumental stuff on it. There was a country song a few years back called "Thunder rolled" about domestic violence.
I think it was either Garth Brooks or Clint Black.
A good instrumental would be Flight of the Bumblebees |
