Sia is paying her respects to the 49 innocent victims of the Orlando Pulse nightclub massacre in her new music video, “The Greatest.”

The video stars 13-year-old dancer Maddie Ziegler who has previously appeared in Sia’s videos for ‘Chandelier’, ‘Elastic Heart’, ‘Big Girls Cry’ and ‘Cheap Thrills’.

Ziegler, who sports rainbow tears on her cheeks, is joined by 49 young dancers who end their dance routine with a haunting sea of lifeless bodies on the dance floor.

Watch the moving tribute below:
