Rookie girl group Billlie is set to drop its original sound track album at 6 p.m. Tuesday, according to its agency Mystic Story.

Titled "the collective soul and unconscious: chapter one Original Soundtrack from "what is your B?," the album includes the lead track "a sign ~ overture to Billlie." It also includes nine other songs such as "prologue ~ 1/1," "welcome to the strange world ~ GGMGY," "M◐◑N in the fog," "epilogue ~ reprise" and "a sign ~ overture to Billlie reprise."

The agency said Jung Dong-hwan of MeloMance took the lead in producing the group's upcoming album.

It is said to be an original soundtrack album because it is comprised of a series of music that was played during the group's 11-minute concept film "what is your B?"

The concept film was released ahead of the group's second EP "the collective soul and unconscious: chapter one” which dropped on Feb 23.

"the collective soul and unconscious: chapter one” saw international success, topping iTunes charts in five regions including Turkey, Finland and Egypt.

The EP's title track "GingaMingaYo (the strange world)" ranked No. 1 on local music charts after its release as well.

The seven-member girl group debuted in November last year with the EP “the Billage of perception: chapter one.” The group started off with six members, but after Mnet’s music survival program “Girls Planet 999” (2021) ended, member Sheon joined the group.

The group is Mystic Story’s first girl group. It represents other artists like Yoon Jong-shin, Cho Jung-chi, Jeong Jin-woon of 2AM, Eddy Kim and Jung-in.

Billlie is comprised of Siyoon, Tsuki, Sheon, Suhyeon, Haram, Moon Sua and Haruna. The name of the group represents that “anyone can have an inner ego to express their B-side.”
