A twist in the opening

I was thinking about a twist in the opening scene, so it starts with a slow blurred opening calming music and when the artistic blurred opening similar to the start of crash, and then after the credits the blurry artistic part of the opening comes into focus and you realize what you have been looking at as beautiful and calming is something like a bunch or drunk teens pulling a moonie at the the main character or the public just generally acting stupid in the street at night. The kind of start that confuses the audience at the very start and makes them wonder "Am I watching the wrong film?" and then as the blur comes to focus the soundtrack completely changes and the mood switches very fast. Im not sure about the drunk teens bit but it would have to be something not expected, i'm not sure about the moonie bit, i would have to film it cleverly to make sure its not to much.
