Sia may still be shielding her face with those elaborate wigs and costumes, but she's very much "Alive." Just days after announcing and teasing her new single, on Thursday (Sept. 24) the lead single from her new album This Is Acting. The song, originally intended for Adele's new album 25, now is perfectly placed in Sia's discography.

"I was born in a thunderstorm / I grew up overnight / I played alone, I played on my own / I survived," Sia sings with a throaty, dignified resilience at the top of the song. As could be assumed from the opening lyrics and the song's title, "Alive" is about overcoming adversity. With empowering lyrics layered over bombastic drums and dramatic pauses, there's an adventurous tone to this song, adding to its raw power. And, of course, Sia nails the vocals, taking everything to unexplored heights.

And though the song fits Sia's powerhouse vocals perfectly, it's clear with certain intonations and in the way that this song builds that it could have gelled well as a new Adele cut. And, if this is the sort of song that she rejects, you just have to wonder what her new album will actually sound like.

Listen to Sia's new song "Alive" below:

"Alive" is Sia's first new single since the release of her stunning 2014 album 1000 Forms of Fear. The track leads the release of her new album This Is Acting, which is due for release by the end of the year. Like how "Alive" was originally penned for Adele, each song on Sia's new LP was originally written and intended for another artist.

See More Sia, Adele
