From debut to now

  • 2014
    First Flow and Delilah made the debut, and later the same year Second Flow and Bad Mama Jama deepened the hip-hop colour.
  • 2015
    Activity widened to the Japanese debut Delilah -Japanese Ver.-, the 3rd Korean mini Incant with Obliviate, and the Japanese song 1,2,3,4.
  • 2016
    The departures of Z-UK and Kichun were announced, a run-up from the early five-strong form toward the later one that makes member histories worth reading apart.
  • 2017
    Stardom came from a lineup including Euijin, Sungmin and Lex, and the context of The Unit later became a door of its own.
  • 2018
    Emphas!ze and Upside Down left the signature songs of late BIGFLO, and the solo route around Euijin grew stronger.
  • 2019
    Reports of contract endings for Ron, HighTop, Jungkyun and Yuseong made it necessary to read current and former members separately.

KPOP DISCOVER's BIGFLO note

BIGFLO debuted in June 2014 with Delilah as a nine-piece. Jungkyun and Hightop took part in the writing and the rapping, so the texture of the songs was easy to read from outside, which marked the early years. With hip-hop as the axis, Bad Mama Jama on Second Flow pushed that roughness and drive further forward, and in 2015 the Japanese-facing 1,2,3,4 arrived, widening the range of activity early on.

To trace the change in the music, the plainest path is to start at Delilah and move to Obliviate. Obliviate, from Incant, has a strong dark texture, and the distance from the debut song gives the swing of early BIGFLO. Because the members were so involved in making the records, each release carries a clear sense of renewal, and following mini albums rather than single songs brings the context out.

Z-UK and Kichun left in 2016, and in 2017 a lineup including Euijin, Sungmin and Lex put out Stardom. After that release, which begins the later period, Upside Down from Emphas!ze left the signature song of those years. In 2019 the end of contracts for Ron, HighTop, Jungkyun and Yuseong was reported, so the early and later lineups need following apart. Delilah, then Obliviate, then Upside Down covers the axis of the debut, the dark swing and the signature song of the later years.

Editors' take Delilah / Obliviate / Upside Down — three songs run a self-written hip-hop line from the early years to the late ones in a nine-piece out of HO Company.

Japan activity score

KPOP DISCOVER original metric
No. 110/ 210 groups

No. 110 of 210 groups with recorded activity in Japan (top 52%)

  • 2Japanese releases
  • 4Japan-related tracks
  • 0Members from Japan
  • 1Official Japanese accounts

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.
