When you have to compete with only your voice, who will be the last singer standing? “King of Mask Singer” is a South Korean variety show where the participants compete against each other wearing masks to hide their true identities. The contestants may be famous singers or stars who have always aspired to sing – but they all have one thing in common. They must all compete with their vocals alone because no one will know their true identities until the very end! Enjoy these highlight clips from the popular variety show, featuring MCs Kim Sung Joo and Kim Goo Ra.
