[1] The original concept of the show aimed to discover young talents in Cantopop and involved sending the contestants to different parts of the world for musical training.

[2] In November 2020, fifteen contestants were introduced to the public through a group performance on TVB's 53rd Anniversary Gala show.

[5] Originally planned for February or March 2021, the competition faced a delay due to a management shake-up at Voice Entertainment, finally commencing in April 2021.

[6] In early April, additional promotional footage titled "Prequel" introduced actor Sammy Leung as the host and singer Hacken Lee as the coaching supervisor.

[8] The show's eponymous theme song was then digitally released on 9 April 2021, accompanied by a music video featuring all the contestants.

With Hacken Lee as the coaching supervisor, the Red Team was led by Vincy Chan, Pakho Chau, and JW.

Under guest host Alan Tam's guidance, the teams engaged in another series of one-on-one battles, competing for the higher number of match wins.

[31] Yiu, Yim, and Chung also received significant media coverage and were considered popular among the viewers, contributing to the overall success of the show.

[58] The top five finalists—Gigi Yim, Chantel Yiu, Yumi Chung, Archie Sin, and Rock Ho—became the first artists to launch their solo careers under the label.

[note 8] In addition to the solo endeavors, All About Music also formed a girl group called After Class which included Gigi Yim, Windy Zhan, Chantel Yiu, and Yumi Chung.

[60] The contestants made their acting debut starring in the musical television series Forever Young at Heart (2021—2022).

[62][63] The concert ran from 12 to 15 August 2021 at MacPherson Stadium, featuring a setlist primarily consisted of songs performed by the contestants during the singing competition.

[65] The contestants reunited two years later for What We Become Live, a concert that took place on 22 December 2023, at Kowloonbay International Trade & Exhibition Centre.
