Sia’s new single “Alive” is a barnstorming operatic howler that was originally intended for Adele’s forthcoming album 25. (Sia co-wrote it with Adele and Tobias Jesso Jr.) Instead, it’s leading off This Is Acting, Sia’s forthcoming LP of songs written for other people. And like the clips on her last album 1,000 Forms Of Fear, the new video for “Alive” features a bewigged stand-in for Sia doing something very impressive. This time around, it’s a very small child, in a two-toned Sia wig, doing a fast and sharp and impressive display of martial arts. She’s by herself in a huge room, so she’s not actually kicking anyone’s asses, but you just know she could. It’s a vivid and memorable clip, and you can watch it below.

This Is Acting is out 1/29 on RCA. Check also the new single “Bird Set Free.”
