I recently saw a music video at a friends house but I can't remember the name of the song artist. I was hoping someone could help me with that based on the description of the video as it's somewhat unique.

It features a black female lead vocalist singing in a large temple/colloseum type building. At the beginning of the video she is surrounded on either side by two huge stacks of PA speakers. Soon in to the video the PA speakers are suddenly levitating 20 feet off the ground.

There are a bunch of awesome dancers in the video too, wearing spooky masks made out of potato sacks among other things, and body paint. The music itself is electric dance music in the vein of Latch by Disclosure.

Anyone, please?
