Why SIA not show your face?

All SIA know as the voice behind the hit "Chandelier", but the artist nominated for the Grammys is really shy when it comes to appear in public. The singer has a perfect explanation about why choose covered.

At the Billboard Awards 2013, SIA wrote for opening a "Manifesto Anti Fame" in which he explains, finally, why hate fame.

"If someone who is not famous know what it means, never wanted to be famous. Imagine the typical mother with hard and completely uninformed opinions and apply it to all adolescents with computer world. Then Throw in boring people, and those whose job is to report on the lives of celebrities. Imagine that strength, that monster criticizing you every day, "she said.
                                                                                                   

Earlier, in an interview on Nightline in 2014, Sia had explained: "I will not criticize me for the way I look on the Internet. I wrote songs for many famous and then to see how their lives are not something you want to me. "
