3rd generation · J. Tune Camp / GNI Entertainment
マッドタウン / 매드타운
MADTOWN were the first hip-hop-leaning boy group from J. Tune Camp, arriving in the wake of MBLAQ.

Last updated:
Moos, Daewon, Lee Geon, Jota, Heojun, Buffy and H.O packed a surprising amount of change into a short run, ending on something much sadder than they started with.
Come here for a group that got noticeably better right up to the point where it stopped.

MADTOWN debuted on October 6, 2014 as the hip hop boy group of J. Tune Camp with YOLO. The line-up of Moos, Daewon, Lee Geon, Jota, Heojun, Buffy and H.O drew notice as juniors to MBLAQ at the same label. Beginning with Mad Town and running through the second release and OMGT the following year to Emotion in 2016, four records were left for the Korean and global markets, along with Japanese versions of YOLO and New World.
The four to hold on to as a way in are YOLO, New World, OMGT and Emptiness. From the bursting hip hop pop of the debut period to the dance-heavy line of the 2nd mini album, then the colourful character turn of OMGT and the aching feeling Emptiness showed in the Emotion period of 2016, the colour of the music shifts clearly inside a short run. The lightness of the formations and the movement reads best in the dance practice for YOLO.
The move from J. Tune Camp to GNI Entertainment came in 2017, but contract trouble made carrying on as a group difficult. Daewon and Lee Geon then appeared on The Unit, while Jota widened his name through acting and variety on shows such as Real Men on MBC. Having several entrances from the group to individual careers and back again is what marks MADTOWN out. Follow YOLO with OMGT and close on Emptiness for the brightness of the debut, the character turn and the later feeling.
Editors' take YOLO / OMGT / Emptiness — the shift from brightness to emotional expression in three songs, from a seven-piece out of J. Tune Camp.
No. 131 of 210 groups with recorded activity in Japan (top 62%)
The denominator is the 210 groups, out of 525 covered by KPOP DISCOVER, whose raw score reaches at least one point. The score adds 10 points per Japanese-market release, 3 per Japan-related track, 12 per member from Japan, and 8 per official Japanese account. Japanese-market releases carry the most weight because they are the most direct evidence of activity; related tracks add track-level detail; members from Japan stand for Japanese-language communication and continuity; official accounts stand for a permanent point of contact. The weights are an editorial judgement, not a statistical optimisation, and the ranking tracks release volume in Japan closely.
