It's been a while since I saw it, but I was thinking Freebird was playing as they went charging towards the police roadblock at the end of the movie.
THe part I'm referring to is when the cop comes to the house and finds a bunch of cheerleaders in the shed. As he comes out into the yard, i forget what happens but the main character(blonde long hair guy, forgot his name) gets him on his knees while pointing a gun to his head. Its like a 1 minute long scene of him just standing there pointing the gun at him as its slowly zooming out before he actually shoots him. It was either freebird playing or comepletely silent with no music. Dont remember, that shit was a long time ago.
Sin City - 10/10. I didn't think id enjoy this but loved it from start to finish, fantastic film and very different from your average movie. The way the movie was made is wicked, highlighting only the important parts with color.. great stuff.
