I love animation and NYC street inspiration. This seems to be a riff on Nick Park's brilliant Creature Comforts. If you haven't seen that and like this, check it out.
I live for spontaneous street parties. When I was a kid growing up in the suburbs I would stare out my window into the empty cul de sac, listening to 'Feel the Beat and the Rhythm of the Night...' on the radio, and imagine the quiet dead end street transforming into a giant dance party. I thought that was what New York City must be like all the time.
