From debut to now
- 2014First Flow and Delilah made the debut, and later the same year Second Flow and Bad Mama Jama deepened the hip-hop colour.
- 2015Activity widened to the Japanese debut Delilah -Japanese Ver.-, the 3rd Korean mini Incant with Obliviate, and the Japanese song 1,2,3,4.
- 2016The 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.
- 2017Stardom came from a lineup including Euijin, Sungmin and Lex, and the context of The Unit later became a door of its own.
- 2018Emphas!ze and Upside Down left the signature songs of late BIGFLO, and the solo route around Euijin grew stronger.
- 2019Reports 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.
Trivia worth knowing
Production
Members had a hand in production on the early releases, which pushes the hip-hop colour past standard idol fare.
Japan activity
Delilah -Japanese Ver.- and 1,2,3,4 are the key releases for Japan, without which the career story breaks off.
Line-up
Current and former members need separating, so the present line-up and the history behind older releases are best read as two threads.
The Unit
Euijin drew wide attention on The Unit, which became a strong personal route back into later BIGFLO.
Signature song
Taking Delilah, Bad Mama Jama, Stardom and Upside Down in order traces how the sound changed from first to last.
Videos
Adding Dance Practice and stage footage to the music videos brings out how hard BIGFLO hit on both rap and dance.

Japan activity score
KPOP DISCOVER original metric
No. 121/ 241 groups
No. 121 of 241 groups with recorded activity in Japan (top 50%)
- 2Japanese releases
- 4Japan-related tracks
- 0Members from Japan
- 1Official Japanese accounts
The denominator is the 241 groups, out of 564 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.
