Stellar 스텔라 is a girl group whose line-up is composed of Gayoung, Minhee, Hyoeun, and Jeonyoul. Formed in 2011 by The Entertainment Pascal, the group attracted attention as they were initially produced by Eric Mun of the boy band Shinhwa. Following an unsuccessful debut with the single "Rocket Girl" in August 2011, Stellar underwent a line-up change and released "UFO" in February 2012, which fared similarly.
The group began working with production team MonoTree in July 2013, and released "Study," which experienced modest success and became their first single to chart in the top 100 of the Gaon Digital Chart. Stellar earned notoriety in February 2014, when they adopted a more "provocative" image for the release of their first extended play Marionette. The album's title track peaked at number thirty-five on the Gaon Digital Chart, making it their most commercially successful single thus far. This stylistic change in direction would be maintained in Stellar's subsequent releases "Vibrato" in 2015, and their second extended play Sting in 2016.
The formation of Stellar began as early as 2010, when Top Class Entertainment reported that Kim Gayoung had signed an exclusive contract with the company and would be joining a five-member girl group. Gayoung had gained attention for her appearance on the "Viewers' Tour" episode of "1 Night 2 Days" and had been cast in the drama series "Poseidon" alongside Top Class Entertainment operator and Shinhwa member Eric Mun. The series was set to air on the SBS network until production halted following the November 2010 Yeonpyeong bombardment incident. The roles were subsequently recast when production was greenlit by KBS a year later. Gayoung was later cast in the 2011 drama "Spy Myung-wol" along with Eric.
The final debut line-up of Stellar was Gayoung, rookie Jeonyoul, and ex-Honeydew members Leeseul and JoA. The group officially debuted on August 28, 2011, with the release of the digital single "Rocket Girl." On January 26, 2012, it was announced that Leeseul and JoA were leaving the group and would be replaced by Minhee and Hyoeun for their first comeback track "UFO."
On July 11, 2013, Stellar released their third digital single, "Study."
On February 12, 2014, Stellar released their first extended play, Marionette. The group received criticism for their "stripping game" promotional material, which involved fans having to "like" posts on Stellar's official Facebook page to reveal photos of the members' body parts. The group received further criticism for their 19+ music video and performances of "Marionette". Despite the controversy, "Marionette" became their best selling single, peaking at number 35 and 34 on the Gaon and Billboard K-Pop Hot 100 charts, respectively.
On August 21, 2014, Stellar released the digital single "Mask."
On March 9, 2015, Stellar released digital single "Fool" and its music video. On July 20, Stellar released the single "Vibrato" and another controversial music video, gaining more recognition. The group responded to criticism of their revealing performance outfits with the explanation that "Vibrato"'s sexy music video was merely meant to be an expression of the group's unique identity. While promoting "Vibrato," Stellar released a virtual reality clip of a July 27 performance. The video, created by virtual reality company Moovr, allows viewers to use their computer mouse or move their smartphone to scroll around a 360-degree rotating view of the stage as the four members perform.
On January 8, 2016, it was announced that the group would return on the 18th with their 2nd mini-album, titled Sting. The album's creation was supported in part through a Makestar-hosted crowd-funding campaign. The campaign's original goal of $8,418 was reached in only three days; ultimately they reached 422% of their goal with $35,510. On January 18, 2016, the album and a music video for the title track "Sting" were released. Stellar explained that their intentions for "Sting" were different from "Marionette" and "Vibrato," stating: "This time, we wanted to look more like a girlfriend rather than to look provocative. We put on lighter makeup, so that more fans will feel closer to us.” The previously released single "Vibrato" was included as the final track on the album.
Stellar announced on April 1 that they would be holding their first solo concert since their debut, on April 22, 2016, at Seoul's Yes24 MUVHALL. They brought to their fans a range of unique performances, including hit songs like "Marionette" and "Sting." The concert was live streamed on various websites such as Allreh TV, Allreh TV mobile, and Goliveconcert.com.
On July 10, 2016, it was officially announced that the group would be releasing their seventh single album called "Cry" on July 18, posting the date of release and the first teaser images for the single through their official Twitter account. This project was also supported, in part, by a Makestar crowd-funding project which raised $53,593 (532% of its original goal). They went on to hold a second concert, Stellar 2nd Concert: After Story, on December 3rd, 2016, while also debuting in Japan with a showcase in Tokyo on August 27th and a concert on December 24th.
