Showcasing their soulful voices,Big Mama is recognized as one of the most talented, if underrated groups in Korean popular music. Made up of members Shin Yeon Ah, Lee Ji young, Park Min Hye, and Lee Young Hyun, Big Mama signed with M Boat Entertainment (a YG Entertainment company) and released their first album in early 2003. As a stipulation in their YG/ M Boat contract, Big Mama members agreed not to undergo plastic surgery - a commonplace activity in South Korea, especially in the music business. The group stayed with YG Entertainment until 2007, citing a lack of promotion by the company. They moved to the Manwalldang group, but quickly faced tension as the company tried to move them from their signature R&B sound to pop music. This tension eventually led to the disbanding of the group in 2011.
Although the group has disbanded, former members Lee Young Hyun and Lee Ji Young continue to release and participate in solo projects under the Taillruns Media group.
