I just love finding promos that are unexpected and break the mold.
The following is a spot from WBZ in Boston. I'm not sure this is exactly the way it aired, as the note on the side says something about slowing it down and adding music.
If anyone knows... let me know. If I'm not mistaken, the former CSD at WCCO(fast becoming my favorite promo shop in the country) is now at WBZ. Very creative work. Check it out.
