CityCenterDC delivers what must be the brightest, retro promotional video that D.C. has ever seen as part of its “District of Joy” campaign. Part ’60s homage, part Austin Powers doppelgänger, this video of dancers in primary colors and memorable wigs sashaying around CityCenterDC conveys the message: we’re smart, we’re stylish, we’re fabulous. I don’t even know some of the references in the video (What is that gigantic cone?), but I watched it twice, and both times with a smile on my face and tapping my foot to the music.
