While New Zealand-by-way-of-Hong Kong vocalist Wing might trigger your memory from a nine year-old episode of South Park singing Abba songs, you might be surprised to find that she actually exists. Her high-pitched, untrained voice accompanied by the cheesiest of synthesizers makes her one of the more unique artists we’ve heard lately, but she covers more than Abba. In fact, she actually has two albums (!) of AC/DC covers. Was she familiar with the band before she covered them? Who knows, but thanks to the AV Club, we now know that her cover of “Back in Black,” stripped completely of any actual rock, is one of the strangest things you’ll hear all day.
