The Four is a television music competition franchise created by British-Israeli production and distribution company, Armoza Formats.
The artists, also known as the challengers, are held in the holding room before singing in front of a live studio audience and the judges.
The panel of people in the music industry ultimately decides the best challengers that compete against "The Four".
After the performance, the judges then vote and make a "Yes" or "No" decision, signifying the challenger's fate in the competition.
If a challenger receives a unanimous "Yes" votes from the panel, they advance to the next round of the competition.
