From Albuquerque to Portland, digital billboards all over the United States will each light up with one line from "The Star Spangled Banner," in a campaign by Clear Channel that is part of the outdoor giant's "United 4th" campaign to showcase its digital out-of-home media abilities. From July 4 to July 7, cities across the country will display lines from the National Anthem. The short film seen here was developed by agency Taxi, and is a sneak peek at what the actual activation is going to look like. An eastern billboard will begin the Anthem, with "Oh Say Can You See," and the activation will close as the sun sets on a Western billboard, with "Home of the Brave."

The Anthem in the film is sung by by singer-songwriter Ingrid Michaelson.
