It’s rare to see a performer that is as authentic as Sia. She has a truly unrivaled passion and emotion is displayed every time she performs. This is truly refreshing in a world of pre fabricated artist and live lip syncing. Sia has a unique background story that deals with severe depression which could be another reason why her passion and emotion is easily seen while performing.
No disrespect to Britney but I would much rather watch Sia in a live performance.
