The just-released music video for Sia’s latest single “The Greatest” evokes the Orlando nightclub shooting that claimed 49 lives in June.

The reclusive singer, who covers her face with wigs and does not appear in her own videos, once again enlists the talents of frequent collaborator Maddie Ziegler.

The video begins with several shots of still bodies and a close-up of Ziegler’s face. The dancer smears rainbow paint on her face, a nod to the LGBT community (the majority of the Pulse nightclub casualties were gay). Ziegler brings the bodies to life and leads them to a large room filled with disco balls and rainbow lights. As the music fades, all of the dancers fall to the ground. Bullet holes can be seen in the wall behind them. “The Greatest” ends with Ziegler in tears.

Sia has not explicitly said the video is about Orlando, but the imagery is quite clear.

49 dancers reportedly participated in the video — one for each Orlando victim. Sia is openly bisexual, tweeting in 2013 “I’m queer. I say queer. I prefer it to all other labels.” She has performed at several LGBT fundraisers and galas, including the Democratic National Committee LGBT Gala in 2014 in front of President Obama.
