Sia made her 'Saturday Night Live' debut last night (Jan. 17) where she performed her hits 'Chandelier' and 'Elastic Heart.'

The 39-year-old Australian singer has rarely made public appearances and usually performs off stage for live show. But for her 'SNL' guest spot, Sia did make an exception by appearing in front of the crowd and cameras, but with her eyes completely obscured.

For her first performance, Sia performed a slowed down version of 'Chandelier' was accompanied by a string orchestra and a mime on stage. As Sia sang on stage, the mime pantomimed to the lyrics standing next to her for the entire performance.

Next, the singer opted to perform her newest single, 'Elastic Heart,' but with her eyes covered again and her position facing to the side of the stage. Two dancers wearing gold leotards then performed an interpretative dance to the lyrics as she sang.
