Next-generation K-POP group KiiiKiii has released a recording behind-the-scenes video for their single “404 (New Era)” on YouTube (video link). The clip shows detailed footage of vocal sessions and rap direction in the studio, offering a rare look at how a 90s house/UK garage–inspired track is actually built.

How “404” balances groove and vocal delivery

“404 (New Era)” is built around a roughly 126 BPM four-on-the-floor groove with strong house/UKG flavour. In the behind-the-scenes video, we see how elements such as:

• low-register talk-singing–style vocal lines
• hook phrases designed for call-and-response
• a heavily sidechained bass and modern synth textures

are adjusted over and over through discussion between the director and the members. Choices like which phrase should become the “everyone can shout this” moment, or how far to push the swing and emphasis, are refined on the spot, revealing a design that targets both the club floor and shareability on social platforms.

Member-led “team production” in practice

One of the most striking aspects of the video is how actively the members participate in shaping the song. Rather than simply following instructions from the producer and engineer, they propose ideas about accents, language balance, and rhythmic feel—co-creating the final lines together.

This reflects a shift away from the older model where trainees mainly “receive” a finished product, toward a co-writing culture in which idols are visible on the front line of the creative process. Especially for club-leaning tracks like “404”, the ability to design how the group moves and rides the groove themselves becomes part of the core skill set.

What recording behind-the-scenes content means for next-gen K-POP

Recording behind-the-scenes videos are no longer just simple making-of clips. For different audiences they function as:

• a document that changes how fans hear the finished song
• a practical tutorial for aspiring producers and songwriters
• a hub that connects short-form and mid-length content on platforms

KiiiKiii’s “404” behind-the-scenes hits all of these points while visualising a next-generation K-POP production environment that updates the house/UKG lineage. As more groups embrace similar content, fans will increasingly experience not only finished tracks but also the layers of process and culture behind them.
