Sia's Coachella Performance was One of The Festival's Best Ever. It's a good thing that Sia performed in the waning hours of Sunday night (Apr. 17) at Coachella, because the singer-songwriter effectively shut down one of the biggest festivals in the world with her live show. Following years of refusing to perform live, Sia offered up a staggeringly imaginative display of artistry at Coachella, composed of interpretative dance, moving performances and awe-inspiring vocal power. 1.
