Authentic, a label under Mound Media, is officially launching the debut project for a new rookie girl band.

Authentic announced that ahead of their official debut, a 'pre-debut documentary' vividly capturing the members' intense preparation process will be revealed for the first time today (the 11th) at 6 p.m. through their official SNS channels.

This documentary highlights the journey of four members, each with distinct personalities, coming together as one band to create music, experience the stage, and grow. From the music production process where the members write songs and practice themselves to the process of taking the actual stage, it will candidly showcase the overall journey toward their debut.

Notably, their skills have already been proven to the public. Authentic's rookie girl band made their first appearance to music fans by surprise as chorus session members during singer Hanroro's performance at 'The Glow 2026' held at KINTEX in Ilsan this past June. Having demonstrated outstanding abilities even before their official debut and drawing attention, anticipation is building for the musical direction they will pursue in the future.
