ZEROBASEONE’s Seok Matthew and Park Gun Wook Form EMP Unit for September 21 Mixtape

ZEROBASEONE members Seok Matthew and Park Gun Wook are opening a new chapter together through a two-member unit named ZEROBASEONE EMP. The project was introduced on September 18 with a logo motion video, establishing the unit’s identity ahead of its first mixtape. The release is scheduled for September 21, giving the announcement a compact, three-day launch window.

The initial reveal is deliberately concise. It confirms the members, the ZEROBASEONE EMP name, the mixtape format, and the release date, while leaving the music itself largely under wraps. No track list, title song, or additional promotional schedule was included in the first announcement. That limited approach makes the logo motion the starting point of the campaign rather than a full explanation of the concept.

A focused two-member project

Placing Seok Matthew and Park Gun Wook in a dedicated unit creates space for a different balance from a full-group release. A two-person format can put greater attention on the contrast and interaction between the performers, while the EMP label gives the project a distinct marker within ZEROBASEONE’s broader activities. The exact meaning or musical direction of the name has not yet been detailed, so the available information supports anticipation without defining the sound in advance.

The mixtape description is also notable. The term often signals a project that can be more flexible in scale and presentation than a conventional album campaign. In this case, however, the announcement has not specified the number of songs, their genres, or whether the release will include a music video. Those details remain open as the September 21 date approaches.

Seok Matthew and Park Gun Wook have already been presented together musically through “Backpacker,” an original soundtrack song connected to the drama Study Group. That earlier pairing gives listeners a reference point for the two members as a combination, but ZEROBASEONE EMP is framed as a separate unit identity with its own first mixtape. The new name therefore turns an existing musical connection into a more clearly defined project.

A short rollout puts the emphasis on discovery

The timing creates an unusually fast transition from announcement to release. With the logo motion arriving on September 18 and the mixtape due on September 21, the campaign leaves little room for an extended sequence of concept photos or song previews unless more material appears rapidly. The structure directs attention toward the release itself and encourages listeners to discover the project’s details at close range.

That short schedule also means the confirmed information should be separated from speculation. The unit consists of Seok Matthew and Park Gun Wook, its name is ZEROBASEONE EMP, and its first mixtape arrives September 21. Beyond those points, the concept, track count, visual style, and performance plans have not been publicly outlined in the launch notice.

For ZEROBASEONE, the unit offers a way to spotlight a specific member combination without presenting the project as a replacement for the group’s main identity. Unit releases can create smaller creative spaces inside a larger act, allowing different vocal colors, performance dynamics, or themes to take the foreground. Whether ZEROBASEONE EMP follows that pattern through high-energy material, a more intimate sound, or another direction will become clearer when the music is unveiled.

What comes next

The next major milestone is now fixed: the mixtape release on September 21. Additional teasers may clarify the songs and visual concept before then, but the opening announcement has already established the core proposition. Seok Matthew and Park Gun Wook are moving from a previous shared soundtrack appearance into a formally named unit, and the first ZEROBASEONE EMP release will arrive only days after the identity was introduced.

The restrained introduction keeps the focus on the partnership. Rather than presenting a long list of details, it asks listeners to follow a simple sequence: meet the unit, note the date, and wait for the music. The debut mixtape will determine how ZEROBASEONE EMP distinguishes itself and what kind of creative role the duo may occupy within the group’s continuing activity.
