Elevating pop music to performance art, Sia performed on Coachella’s main stage with a setlist featuring iconic hits like “Unstoppable,” “Cheap Thrills,” and “Chandelier,” plus covers of Rihanna’s “Diamonds” and David Guetta’s “Titanium,” which she co-wrote. True to her signature style, she kept her face hidden behind her half-black, half-white wig while delivering her anthemic pop hits, leaving the visual entertainment to a rotating cast of dancers and celebrity guests including Kristen Wiig, Paul Dano, Tig Notaro, and Maddie Ziegler.
