This program marks the third installment of the "Hidden Musician Discovery Project" by the JTBC production team behind hit music variety shows like *Phantom Singer* and *Super Band*. It is the first-ever project dedicated to forming an all-female vocal group—a "second Big Mama"—comprised entirely of lead vocalists. Participation is open to any woman eager to explore new musical horizons, regardless of her background or professional status—whether she comes from the worlds of K-pop, musical theater, idol groups, jazz, hip-hop, traditional Korean music, classical vocal music, or is a YouTuber.
