If you thought the music video for Sia's "Elastic Heart" was good [1], just wait until you see this choreography video. The dancers at Urban Dance Camp really turned it out for this one; their moves are just as mesmerizing as the video and Sia's performance on SNL [2]. Things have only been heating up for the emergent music artist lately. In fact, just this week, she released a new song on the Fifty Shades of Grey soundtrack [3]! Watch the video above, because if you're like us, you just can't get enough.
