EvoL

In March 2012, Cho PD announced the upcoming girl group. Although initially intended to debut in April through a variety show,[3] their debut date was changed to August 2012. The group garnered much interest prior to their debut from both domestic and international fans.[4] The group went through member changes before the final line-up was released. Current members Say and J-Da made an appearance in labelmate Block B's music video "NanlinA", alongside two other former members of the group, Song Kwanghee and Lee Dasom, the latter who was formerly a member of the girl group Tahiti. Jucy was also an underground rapper known as "Juni.J", and had released a few tracks of her own, having penned her own lyrics. On July 12, 2012, EvoL's first audio teaser was released,[5] followed by a series of both video and audio teasers that showcased a sample of songs from their EP.

On August 10, 2012 the group released their EP "폭파해줘! (Let Me Explode!)" and an MV for the single "우린 좀 달라 (We Are A Bit Different)". The album consists of five tracks and is available on CD and also for digital download. On August 16, 2012, EvoL made their stage debut with their single "우린 좀 달라 (We Are A Bit Different)" on M!Countdown.[6]

On December 13, 2012, Say tweeted a photo of herself and the other members, with the caption: "It's New EVOL! 보고싶어 많이많이 Guyz how do u do~we miss u so so much..Thanks 4 waiting us. We'll meet u r expectation soon".[7]

On March 6, 2013, EvoL announced their official comeback set for March 18, releasing teaser images of Say and Hayana, while J-DA, Yull and Jucy's teasers were released two days later.[8][9] EvoL then released several tracks from their 2nd mini-album ‘Second Evolution’ on March 18 at noon, with the digital album release on March 19. The offline release of the album was set for March 20.[10] EvoL showed their “crab dance” choreography in the music video for their title track “Get Up“ and released a short 30-second clip teaser of member J-DA riding a mechanical bull.[11]

In the summer of 2013, Jucy released a mixtape, and in May 2015, she joined the cast of Show Me The Money (seasons 2 and 4), only to be eliminated very early on in the competition.[12][13][14]

During the summer of 2015 rumors appeared on fansites alleging that Say's contract with Stardom had expired and that she had left EvoL (while still remaining with Stardom Entertainment), and would redebut as a solo artist. Fans also alleged favouritism from Cho PD on Say's behalf, claiming that they had given her special treatment (giving her time off, allowing her to skip group performances, etc.). Cho PD and Stardom Entertainment have never responded officially to these claims.

In August 2015, it was revealed that Yull, Hayana and J-Da had had their contracts terminated without their knowledge during Stardom's merge with Hunus Entertainment, thus effectively disbanding the group.[15][16]
