Her name is Wing. Wing Han Tsang, to be exact. She's from Hong Kong by way of New Zealand and she's gonna rock your world.....
You might have heard of Wing from an episode of South Park (they dedicated a whole episode to her)
She has recorded 20 CDs of cover versions of songs ranging from Elvis to AC/DC (in fact, she recorded TWO albums of AC/DC covers!)
Here's her rendition of AC/DC's "Hells Bells"
She actually has a huge worldwide fan base, proving that talent and singing on key and coherently are simply overrated.
But sadly in June of 2015, Wing announced her retirement from music.
