Preliminary TOO trainees of 'WORLD KLASS' announced their first appearance on the music show.

The stage was staged by prospective TOO trainees appearing in the global K-pop idol growth journal "TO BE WORLD KLASS" via the World No.1 K-pop chart show Mnet "M Countdown," which aired on the afternoon of Nov. 7.

On the same day, the 20 trainees are scheduled to perform the stages that were released at "KCON 2019 LA," which was released in August.

This is the third world mission that all 20 trainees from the previous "WORLD KLASS" broadcast have passed through.

The World Team, which decorated Billie Eilish's Bad Guy, and the Class Team, which performed Justin Bieber's "What Do You Mean?" reenacted the heat generated at the scene of KCON 2019 LA.

In particular, this is the first opportunity to see prospective TOO trainees on a music show, and the distinction between WORLD KLASS which boasts a different scale, stands out.

Meanwhile, the Global K-pop Idol Growth Diary "WORLD KLASS," which airs every Friday night on Mnet and Naver VLIVE, is a global reality survival program that has taken off the traditional audition formula, among 20 trainees. 

Global Idol Group means 'Operators toward 10 Orient Values' TOO (Ten Oriented Orchestra) members are selected.
