In 30 seconds: LC9

The catalogue is short, so the televised stages, the singing and the members' later work carry as much weight as the releases do.

Come here if you follow the label that also housed Brown Eyed Girls and want to see its boy group.

From debut to now

  • 2013
    LC9 debuted with MaMa Beat, drawing notice for a hard-edged music video featuring Ga In and a performance-heavy colour.
  • 2014
    East of Eden carries a different tune and a different visual mood from MaMa Beat, and marks an important fork inside a short catalogue.
  • 2015
    Put the Say What?! footage of Jun and Rasa together with the later routes of each member, and a person-by-person view of LC9 becomes possible.
  • 2016
    Entering through the later work of J-Hyo, A.O and E.Den makes it easy to go back to the roles held in the LC9 years.
  • 2020
    Set the separate activity of members such as A.O alongside, and even a short-lived group works as a route across K-pop.
  • 2026

KPOP DISCOVER's LC9 note

LC9 took their name from League of Competition #9 and debuted from Nega Network in May 2013 as a five-piece boy group. Rasa, J-Hyo, King, Jun and A.O made up the lineup, and the debut song MaMa Beat left an early mark with a rough-cut music video featuring Ga In and a sharp performance. The active years ran only from 2013 to 2015, yet the short catalogue reads all the denser for it.

MaMa Beat is close to the only door there is. Footage that turns roughness into a weapon arrives at the same time as a group dance whose force all points one way, and the pull it has runs on an axis away from polish. East of Eden, from July 2013, swings that mood completely around and steers toward a calm tone you would not think came from the same group. Those two songs alone give a large sense of how far the swing could go.

From 2015 the group stopped and the members went separate ways. A.O carried on in contexts far from the LC9 years, taking part in Produce X 101 among other things. Some joined the later groups LU:KUS, BLK and NIK, so LC9 works as a starting point for crossing third-generation K-pop more widely. MaMa Beat, then East of Eden, then Say What?! covers the raw heat, the quiet swing and the character of the members.

Editors' take MaMa Beat / East of Eden / Say What?! — raw heat and a quiet swing across three songs, from a Nega Network five-piece.
