Watch: Sia's latest single 'The Greatest' is a touching tribute to Orlando shooting victims

Sia's back and how!Apart from hitting the billboard this time, she hard-hits the walls of your heart as well. Her latest release, 'The Greatest' featuring rapper Kendrick Lamar, not only has all the beats you'd expect from a Sia song, but also sends out a strong message.With her music video, Sia takes us back to the month of June, where she reminds us of the victims that were wronged in the Orlando mass shooting. The 49 dancers in the video deliver a powerful performance that's led by Sia's regular collaborator Maddie Ziegler.While Sia has not officially confirmed this yet, instagram posts from a few of the performers in the video clear the air.[caption id="attachment_2995656" align="alignleft" width="380"] Maddie Ziegler from Sia's music video of 'The Greatest'[/caption]The video opens with Maddie Ziegler painting her face with rainbow colours and stumbling over bodies that lie on the floor. They eventually wake up and dance their aggression out.It ends with the performers lying motionless in a nightclub like set-up, revealing bullet-pierced walls in the background.Here's what typically defines a Sia video: Maddie Zeigler, Maddie Zeigler's expressions, Maddie Zeigler's dance moves, Maddie Zeigler's unbelievable stretches. To know that the blonde-haired Zeigler has been replaced by a black-haired Zeigler makes an instant connect with me.So what makes 'The Greatest' so great? To have Maddie lead a 49-member dance crew, while each one of them carry expressions that deliver pure magic and energy.Watch the video here:
