The queen of loving cheap thrills, Sia, dropped a surprise new single and video “The Greatest” yesterday for the victims and families of the horrific Orlando shooting. Led by dancer and muse Maddie Ziegler, it’s a haunting visual masterpiece that will leave you in chills. (And, the song is great too!) Kendrick Lamar lends his incredible vocals as well.

Check it out:

The single is available on iTunes.
