KARA Biography (Wikipedia)
Kara (Hangul: 카라, Japanese: カラ, often stylized as KARA) was a South Korean pop girl group formed by DSP Media in 2007. The group's final lineup was composed of Park Gyuri, Han Seungyeon, Goo Hara and Heo Youngji. Members Nicole Jung and Kang Ji-young officially departed from the group in 2014, while Kim Sung-hee left in 2008. The group's name comes from the Greek word "chara" (χαρά, lit. "joy"), which they interpreted to mean "sweet melody".
The group originally started off as a quartet and made their debut with "Break It" (2007) while displaying a strong female image and a mature R&B sound. Expectations for the group were big because they were considered as successors to their senior labelmate, Fin.K.L. They released their first studio album titled The First Blooming in March 2007. However, their debut was not well received by the public and was a commercial failure. The following year, Kim Sung-hee departed the group due to parental pressure, and members Goo Hara and Kang Jiyoung were brought in. After their addition, the group also changed their musical style and their image to the "pretty but natural" appeal, releasing their first mini-album, Rock U in July 2008. They achieved their first number one song with "Honey" (2009). In July 2009, the group released their second studio album, Revolution and spawned the hit single "Mister", whose choreography featured the "butt-dance", that helped increase the group's popularity within East Asia. Their follow-up singles including "Lupin" (2010), "Jumping" (2010), "Step" (2011), and "Pandora" (2012) were also successful and helped further establish the group within the Korean music industry. The group were ranked at No. 6 and No. 5 in Gallup Korea in 2009 and 2010 respectively, thus making them the second best girl group in Korea for 2010. They were also ranked at No. 4 and 13 in February 2012 and 2013's Forbes Korea Power Celebrity list.
