Over a month after announcing their disbandment, 2NE1 revealed that they will have a final comeback with a farewell single later this month. On Jan. 5, their label, YG Entertainment, announced that the trend-setting K-pop group will release “Good Bye” on Jan. 21.

The news came several weeks after 2NE1 members shared their regrets on social media for suddenly disbanding after previously teasing new material. According to YG Entertainment, “through the new single, the group will express how sorry they are.”

“Good Bye” will be the first new music from the girl group since 2014’s Crush album, and the only song without member Minzy, who left 2NE1 several months before the group officially broke up in November. The quartet’s other members -- CL, Park Bom, and Dara -- will feature on the new single and appear in an accompanying music video. Only Dara and CL remain under contract with YG, while Minzy is currently preparing a solo debut and signed to Music Works Entertainment.

The act were gearing up to release their first new music in years as a trio last year after being on hiatus since 2014. However, YG Entertainment announced their disbandment, putting to rest comeback rumors. Their last single as a quartet, “Gotta Be You,” was released in 2014 and commemorated their fifth anniversary.

2NE1 was formed in 2009 and subsequently became one of K-pop’s most prominent acts through their empowering, modernist pop image. They had numerous hits, including “Lonely,” “Can’t Nobody,” “I Love You, and “I Am The Best,” the latter of which was featured stateside in a Microsoft computer ad. Throughout their seven years together, 2NE1 also saw members release solo music and gain recognition internationally as style icons.
