"49 beautiful lives lost. This is for you," one of the video's dancers writes.
Late Monday, Sia and Kendrick Lamar released new track "The Greatest" and an accompanying video starring Sia favorite Maddie Ziegler -- though this time, she's not alone. The video -- which opens to a black screen with the hashtag #WeAreYourChildren typed in white font -- sees Ziegler accompanied by a large sum of dancers (49 in total), which is said to represent the 49 lives lost in the shooting at Orlando nightclub Pulse.
Matt Moseley, one of the dancers in the video, posted a screengrab to Instagram with the caption "49 beautiful lives lost. This is for you."
