Completely Different Idea

This isn't at all related to my earlier idea...

A musical piece composed of many different sounds found in the city. It would be a fast beat that would always have multiple parts going on at once, and be split up into a few parts. It would start with more of a construction site feel: clinking metal, hammering, power tools, and slowly transition toward big construction vehicles. Slowly the vehicles would turn into cars, until you realized you were in traffic during rush hour. You would move past cars onto public transportation, and it would focus on the conversations going on around you, with cell phones and stuff like that. The conversations would slowly give way to an argument on the street involving a construction worker, then end in the same style that it began.
