Sia took the stage at this year's Coachella and she stole the limelight of the headliner of the final day: Calvin Harris. This was her first full concert since 2011 and it was amazing! She was joined by Maddie Ziegler, Kristen Wiig, Paul Dano, and Tig Notaro, and gave a memorable performance of her hit singles Alive, Chandelier, Bird Set Free, Cheap Thrills, and more. Her performance of Diamonds, which she wrote for Rihanna, is trillion times better than the latter's version! Enjoy this iconic show below!
