Really liked this video. It's apparently a tribute to the dead of Orlando nightclub shooting, with 50 dancers representing the victims. I think the main young dancer that Sia always uses is a bit of a child prodigy.
EDIT: Well hope you got to see and hear it. It was fabulous.
"Arcade Fire - Lollapaloosa Chicago Live 2017" This video is no longer available due to a copyright claim by C3 Presents.
Sorry about that.
Well here is the closer. Other songs are available individually but not as well recorded as the professional recording previously posted. Wish I had downloaded it from my list.
