Product Research: 'Green Street Hooligans' 2

This is a later scene from the same film 'Green Street Hooligans'. The main factor that I would wish to draw from this is the way the director has chosen to use music to juxtapose the events of the scene. This is something I would be interested in doing, using sad and slow music ad then paring it with horrendous violence. Of course the violence in our scene would be not nearly as harrowing as in this one, but the effect of the music would be the same.
