オンリーワンオブ / 온리원오브
OnlyOneOf work in low, R&B-based art pop and choreograph the distance between bodies as carefully as the steps.
Last updated:
KB, RIE, YOOJUNG, JUNJI, MILL and NINE run a concept that continues even through the capitalisation of the song titles.
Start here for the most intimate staging in Korean pop, handled with more seriousness than the subject usually gets.

Follow a few songs from the starting point to the group's current sound.
savanna MVsavanna is the debut, low and slow, with the original line-up in place.
libidO MVlibidO is the signature, and the video and the practice cut show two different versions of the same idea.
seOul drift MVseOul drift carries the urban pace of the current line-up, on video and on stage.Verified English information is not yet available for this section.

Filing OnlyOneOf under 'sensual songs' blurs the outline. R&B recorded with the voices close and choreography that keeps rearranging the distance between members are drawing the same subject. Play the music video for libidO and then the Dance Practice, and that design shows itself fastest.
Moving from the early savanna and sage on to skinz, seOul drift and dOpamine, the visuals do not get louder; the relationship between gaze and body gets more precise. Follow the Japanese releases as well and it becomes clear that the same aesthetic holds across changes of language and market.
Editors' take Watch past the music videos to the choreography footage and it becomes clear that the sound and the bodies of OnlyOneOf are telling one story.
No. 60 of 210 groups with recorded activity in Japan (top 29%)
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.
