There is something uniquely powerful about a K-pop group performing not on a polished stage with production lights and ticketed seats, but out in the open air of a city plaza where anyone walking past can stop and watch. On June 10, 2026, Billlie did exactly that at Cheonggye Plaza in central Seoul, and what was meant to be a celebratory fan event turned into one of the most talked-about live moments the group has delivered yet.
The occasion was the release of their first full-length album, and the crowd that gathered made it very clear this milestone was not going unnoticed.

What Is “the collective soul and unconscious: chapter two”?
“the collective soul and unconscious: chapter two” is Billlie’s first full-length studio album, marking a significant milestone in the group’s discography. The album features two double title tracks, “ZAP” and “WORK”, along with a collection of B-side tracks that showcase the group’s range across genres and performance styles.
More than a month after its release, “WORK” continues to rank among YouTube’s daily trending music videos, maintaining strong momentum well beyond the typical promotional window. That kind of long-tail performance is a clear indicator that the album has connected with audiences beyond just the core fanbase.
The Full Setlist
Billlie structured the busking performance to cover both title tracks and key album cuts, giving the crowd a genuine taste of the album’s full range.
| Order | Song | Notes |
| 1 | ZAP | Double title track, opened the event |
| 2 | SOUPASTA | B-side, known for its playful, kitschy sound |
| 3 | OFF-AIR | B-side, groove-driven and sophisticated |
| 4 | WORK | Double title track, powerful finale |
| 5 | RING Ma Bell (what a wonderful world) | Encore, performed in response to crowd demands |
What Made the Performance Stand Out
The crowd reaction at Cheonggye Plaza was immediate. Billlie opened with “ZAP”, and the energy from the rapping and dynamic stage presence grabbed attention right from the start. However, it was the performance of “WORK” that became the visual centrepiece of the event.
The choreography for “WORK” draws heavily from voguing, with synchronized group movement and what the group’s agency described as “delicate control of dynamics.” The combination of intricate formation shifts, intensity changes, and the visual precision of the routine was striking enough to stop passersby who had no prior context for who Billlie were. People walking through Cheonggye Plaza simply stopped and stayed.
The encore was not planned, but the crowd made it happen. After “WORK” closed the set, fans continued calling for more, and Billlie responded with a performance of “RING Ma Bell (what a wonderful world)”, which brought the event to an enthusiastic close.
After the performance, the members addressed the crowd directly:
“We were surprised that so many people came to see us. Thank you so much.”
What Is “Billlie-core”?
If you are newer to Billlie’s world, the term “Billlie-core” comes up repeatedly when fans and the group’s own agency describe their artistic identity. It refers to the way Billlie connects music, performance, and visual concept into a single cohesive experience rather than treating them as separate elements.
Their agency described the busking event as another proof of this identity, stating that Billlie “once again proved the true value of Billlie-core, where music, performance, and concept are organically connected, as they freely crossed various genres.”
For fans of games with deep lore and interconnected world-building, the idea of an artistic identity built on organic connection across multiple creative layers is a familiar and satisfying concept. Billlie operates with that same kind of intentional consistency.
Why This Busking Event Stood Out?
Billlie organized the event specifically as a thank-you to fans for their support of the new album, choosing a public outdoor space rather than a formal venue. That decision made the performance accessible to anyone in Seoul that day and gave the group a chance to connect directly with both dedicated fans and curious newcomers.
The choice to include B-side tracks alongside the title tracks in the setlist was deliberate. Rather than limiting the performance to the most commercially visible songs, Billlie used the event to demonstrate the full depth of “the collective soul and unconscious: chapter two” as an album worth listening to front to back.
The response confirmed that the approach worked. The crowd that gathered did not thin out as the set progressed. It grew.
Billlie’s first full-length album “the collective soul and unconscious: chapter two” is available now on all major streaming platforms including Spotify and Apple Music. You can also watch the official music videos for “ZAP” and “WORK” on Billlie’s official YouTube channel.
