EXID is a five-member South Korean girl group under Banana Culture. The group consists of Solji, LE, Hani, Hyerin and Jeonghwa.
They made their official debut on February 16, 2012 with their single HOLLA, promoting the title track, "Whoz That Girl". The group originally debuted with six members, but three members (Yuzi, Dami and Haeryung) decided to leave the group two months after the group's debut, and were replaced by two new members, Hyerin and Solji. Later, the members who left re-debuted in BESTie under YNB Entertainment.
On August 24, 2014, EXID held their comeback showcase at the Ilchi Art Hall, performing their new song "위아래 (Up & Down)". The song was released on August 27 and initially charted poorly, failing to make it on the top 100 on the Gaon Chart; though it peaked at number 94 on the domestic chart. However, the song slowly gained popularity in late November after a fan-cam of member Hani performing the song went viral on Korean social networking websites. This lead to the song shooting back up on the music charts, eventually climbing up into the top 10 on the real-time charts and topping the Gaon Chart.
