Sia and Kendrick Lamar have released a new track titled ‘The Greatest’ and an accompanying video starring Sia’s favorite dancer Maddie Ziegler and she’s not alone this time.

The video opens to a black screen with the hashtag #WeAreYourChildren & Ziegler is accompanied by dancers (49 in total), which is said to represent the 49 lives lost in the shooting at Orlando nightclub Pulse.

The video concludes with the young dancers moving and shaking in what vaguely represents a nightclub setting, before all falling to the ground, which in turn exposes the bullet-pierced wall behind them.
