They were one of the first (If not the first) Korean groups to head over to Japan. That was back in 2004/2005. They released two albums and four singles but never made it big.
The group has been around since 2001 and has released 6 albums, 3 repackaged albums and 3 digital singles (Not counting their newest one)
(Now for the hard part~)
Original members were Park Jung Ah, Jung Yu Jin, Jun Eun Mi and Lee Ji Hyun. Jung Yu Jin and Jun Eun Mi left in 2002 and were replaced by Seo In Young and Cho Min Ah. Lee Ji Hyun and Cho Min Ah left the group in 2006 and were replaced with Eun Jung and Baby-J. In 2009, Seo In Young and Park Jung Ah left the group. Park Jung Ah being the last remaining original member. In 2010, Se Mi, a top 10 finalist from the first season of Superstar K joined gthe group and then in 2011 Ye Won was also added to the group. (Did you get all that?)
So now the group is, Baby-J, Eun Jung, Ye Won, and Se Mi.
And they are making a real comeback with their digital single, Back It Up! (Watch the MV) (It's cheesy goodness~)
They've come a long way since 2001 and from their wiki page it seems the company was going to ditch their name and re-brand the group. Glad to see they didn't.
