T-ARA

T-ara is a South Korean girl group formed by MBK Entertainment in 2009, consists of four members: Qri, Eunjung, Hyomin and Jiyeon. T-ara's career is marked by hook-heavy dance-pop music, a result of their close partnership with composer Shinsadong Tiger. A broad array of visual concepts have earned the group a "chameleon-like" reputation. The group has achieved commercial success in several regions in Asia including South Korea and China, with their single "Roly-Poly" being one of the most downloaded domestic singles since 2010.
T-ara made their debut with the single "Lie" in 2009, following line-up changes due to creative differences; their debut studio album Absolute First Album was well received critically and spawned the hit singles "TTL", "Bo Peep Bo Peep", and "You Drive Me Crazy". Both their debut Japanese single and studio album reached number one on the Oricon weekly charts and were subsequently certified Gold. They subsequently gained nationwide recognition after releasing "Roly-Poly", which went on to become the Gaon chart's best-selling single of the year.
