While the format originated in South Korea as King Of Mask Singer, the American iteration has since been replicated worldwide in Australia, Germany, Russia and the UK.
In the first season, professional singers dominated the twelve-person lineup, including Gladys Knight, LaToya Jackson, Donny Osmond and T-Pain.
Of season two’s 18 competitors, eight had sung professionally in their past, with acclaimed vocalists such as Seal, Patti LaBelle, Chris Daughtry and Adrienne Bailon taking part.
The show faced backlash on April 15 for airing a karaoke-based “sing-a-long” special instead of an actual episode, during which old clips of the remaining seven contestants were replayed with subtitled lyrics.
The Masked Singer airs on FOX.
