King of Mask Singer

The King of Mask Singer  is a South Korean singing competition program presented by Kim Sung-joo, with introductions by voice actor. It airs on MBC on Sunday, starting from April 5, 2015 as a part of MBC's Sunday Night programming block.

Format
Each competition lasts for two episodes, with the singers competing one-on-one in three elimination rounds. They are given elaborate masks which are made by designer and gloves to wear in order to conceal their identity, thus removing factors such as popularity, career and age that could lead to prejudiced voting. In the first round, both contestants sing the same song, while in the second and third round they each sing a solo song. The winners of each pair are selected by the audience and panel of celebrities through instant live votes. The identities of the singers are not revealed until they have been eliminated. The winner of the third round challenges the previous competition's Mask King, and is either eliminated or becomes the new Mask King. Ha Hyun-woo of Guckkasten ("Music Captain of Our Local") and Yunmin of ("The Joys And Sorrows Also Count As Rock") have nine consecutive wins, which is the highest number of wins achieved by any contestant (and highest number of both males and females)

Due to great interest and demand, the show released a special album consisting of a selection of studio recordings by the competitors.
