0129-main-sia-splash-02Sia had a big reveal Friday ... in her face!

The singer walked along a street in NYC with her hair pulled back ... not a trademark bang in sight.


She was in New York to perform on GMA, where she was in full regalia. 

Funny thing is ... she hardly got recognized.

She don't bang no more.
