## Galas

The Galas or live shows began on 19 September 2018. In the introduction live show or Gala 0, 18 candidates were presented to enter the "Academy." Each contestant performed a cover version of a popular song of their choice, and two of the candidates were eliminated. For the regular galas, the contestants are assigned a popular song to perform in a duet or solo. The audience votes for their favourite performer, and the contestant with the most votes is exempt for nominations. The jury panel comments on the performances and nominates four contestants for elimination. The Academy's staff meeting saves one of the nominees, and the safe contestants save another of the nominees. The two remaining nominees prepare the performance of a song of their choice each for next week's live show, where one of the contestants is saved by the audience via televote, sms and app voting. Each gala features a guest judge and guest performers.
