Kara is a South Korean pop girl group formed by DSP Media in 2007. The group is composed of Park Gyuri, Han Seungyeon, Goo Hara and Kang Jiyoung. The group's name comes from the Greek word "chara", which they interpreted to mean "sweet melody".
The group originally started off as a quartet and made their debut with "Break It" while displaying a strong female image and a mature R&B sound. Expectations for the group to be as big as their senior labelmates, Fin.K.L, were extremely high and the members were promoted as successors to them. 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 Sunghee 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 image and style of music to the "pretty but natural" appeal, releasing their first mini-album entitled Rock U in July 2008. They achieved their first number one song with "Honey". In July 2009, the group released their second studio album entitled Revolution. The album 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", "Jumping", "Step", and "Pandora" were also successful and helped further establish the group within the Korean music industry.
