クナクン / 크나큰

In 30 seconds: KNK

Youjin left, Dongwon joined, and Hyunjong belongs to the later years, so the group looks noticeably different depending on which single you start from.

Choose this if physical presence on stage interests you as much as choreography does.

KPOP DISCOVER's KNK note

KNK debuted on March 3, 2016 as a five-piece out of YNB Entertainment, a third-generation boy group. The name comes from Korean. Tall members gave the silhouette its size, the dancing sat low in the body, and the singing carried weight, which together set the early impression. The debut song Knock and, from the same year, Back Again and U cover the texture of the voices and the dramatic construction of the songs in one pass.

Sun Moon Star and Rain from 2017 mark out a width that reaches past hard-hitting dance tracks, with a neat melody and vocal-led construction to the fore. Rain brings ballad-leaning feeling together with calm visual treatment, so the vocal axis is easy to feel. Set those beside Back Again and the reach of the early sound comes into view.

After the restart that followed a change in the lineup, Lonely Night in 2019 switched the air around the group, and Sunset that same year took the visual beauty and choreographic precision of the later period to a peak. KNK Airline in 2020 gathered the late sound around Ride, and that remains the most recent release to follow. Heard as Knock, then Sun Moon Star, then Sunset, the line from early impact to late refinement holds together.

Editors' take Knock / Sun Moon Star / Sunset — three songs showing how the voices and forms of a tall group changed era by era, from a YNB Entertainment five-piece with a later lineup change.
