"Countdown" by Beyoncé
Channeling 1950s style and a high-energy mix of classic and modern dance moves, Beyoncé's "Countdown" is both technically and visually one of her greatest achievements. Adria Petty directed the music video, and it was shot in 2011 while Beyoncé was pregnant. The choreography references several pop cultur highlights, such as Audrey Hepburn's beatnik dance from Funny Face and the '80s warehouse dancing of Flashdance. It also, somewhat controversially, uses phrases from Anne Teresa De Keersmaeker's Rosas danst Rosas.
