In case you missed this performance at the Grammy awards last night, here is Sia performing her amazing single Chandelier with help from Maddie Ziegler and none other than Kristen Wiig. Kristen really goes for it too and the result, in my opinion, is quite moving. Sia, as usual, faced away from the camera as she has done for all the performances for her album 1,000 Forms of Fear. Her voice is so powerful that she doesn't have to face the audience, y'all!! Enjoy the excellent performance below.
