Check out Sia performing Chandelier on Dancing with the Stars, accompanied by Maddie Ziegler, and Allison Holker. It's literally the most perfect thing I've seen in a while. Sia's voice is magical, and the dancing is impeccable. There's just so much talent on this stage at one time.
I could literally rant for hours about how good this is, and how amazing and raw Sia's voice is, but I'll just let you watch it and judge for yourself!
