Sia has shared a delicate new track "Angel by the Wings," an absolutely stunning cut.

The emotional song is taken from the soundtrack for the new documentary The Eagle Huntress, which tells the story of a 13-year-old Mongolian girl who became the first 12 generations of her Kazakh family to become an eagle hunter. She became the first Mongolian female to compete at the Golden Eagle Festival in Ölgii and win, thus defeating 70 veteran eagle hunters.

The film is currently in select theaters and "Angel by the Wings" can be heard below.
