CLC was originally debuted with five members: Seung-hee, Yu-jin, Seung-yeon, Sorn and Ye-eun. They made their first appearance as back-up dancers for singer G.NA back in 2014. Not only that, but they also modeled for the uniform brand Smart, featuring in a promotional music video with the boy groups GOT7 and B1A4. CLC also appeared on BTOB’s music video for the song Love Confession.

Before their official debut, the group began to gain publicity through street performances that raised money for children with disabilities. These featured on their online reality show, CLC’s Love Chemistry.

CLC debuted in March, 2015, with a five-member lineup. They released their first EP, titled First Love, including the lead single, Pepe, on March 19th, 2015. Pepe is a retro dance song written by Duble Sidekick and Yang Geng. Part of the song’s choreography was put together by singer Rain.

CLC had a debut showcase which was held the day before their music show debut at the Acts Hotel in Seoul, where they performed their debut song for the first time. After that, they made their music show performance debut on Mnet’s M! Countdown.

On April 16, CLC released a digital single, Eighteen, which can be best described as a song about teenage love influenced by 1960s/’70s Motown and 1980s synthpop. They began promotions for the single the following day on KBS2’s Music BankTheir second EP, Question, was released on May 28. Its lead single, Curious (Like), was first performed on M! Countdown.

On October 10–11, the group held their first overseas promotional tour in Malaysia, entitled “First Love Promo Tour in Malaysia”. For the tour, Universal Music Malaysia released an “Asia Special Edition” version of Question. The special version included tracks from First Love and Question, as well as the digital single Eighteen.

CLC’s debut and second mini album were filled with an innocent and cutesy look.



During 2016, CLC began undergoing a transformation, mostly due to the addition of two new members: Elkie Chong and Kwon Eun-bin.

CLC’s third EP, Refresh, and it’s lead single, High Heels, were released on February 29, 2016. This comeback marked the first appearances of Elkie and Eun-bin. The latter’s addition became controversial due to her double role as a participant of Mnet’s girl-group survival show Produce 101 at the time. Cube Entertainment then stated that Eun-bin had been part of the group’s original lineup, but was dropped following delays in the production of the group’s debut album.

Due to Produce 101’s contractual restrictions, Eun-bin was not able to promote the single High Heels on music shows or other broadcasts, nor appear in the single’s music video. The agency planned for Eun-bin to join promotions in the event that she was eliminated from the show, or else to postpone her activities as part of the group until after Produce 101 promotions if she was a winner. On February 29, a short version of the High Heels music video that included Elkie, but omitted Eun-bin, was released. The full version of the music video, including Eun-bin, was released on March 21.

In the same year, CLC also made their Japanese debut on April 13, with the release of their first Japanese EP, High Heels. The album includes the Japanese versions of Pepe, First Love, Like, High Heels, and a cover of Kylie Minogue’s I Should Be So Lucky.

On May 12, CLC launched their official Naver V App channel, followed by a broadcast of Eun-bin’s first live appearance with the group. The group then went into a more funky look with the release of their fourth Korean EP, Nu.Clear, on May 30, with the title track No Oh Oh, written by Shinsadong Tiger. They carried out album promotions as a seven-member group in June.

On July 27, they released their second Japanese EP, ChamismaThe EP peaked at #9 on the Oricon Daily Albums Chart, making it their first release to enter the Top 10 of the Oricon chart.
