Well thats what happened to millions of fans in Korea who were preparing for their favorite group to release their 4th album. The group was on top of the world, gaining more and more love and fans daily.
They were in the studio recording when they suddenly announced they were retiring.
No one knew, or knows, why, including some of the members (like YG himself!) The group was Seo Taiji and The Boys and in 1996 the leader decided the group would disband, and their 4th album became a goodbye album.
Fans were shocked and its still considered one of the most shocking moments in kpop history.
Seo Taiji went to America to study music and then had a successful solo career. YG started YG Entertainment, and the thrid member also found moderate success with his record label too.
Can you imagine how those fans felt and still feel? What a horrible rollercoaster of emotions!
