Hertzwave (하츠웨이브)

Five members, five frontmen — that is the premise hrtz.wav (하츠웨이브) brought to their April 8, 2026 debut. Formed through Mnet's survival program *Still Heart Club*, where each member placed first in their respective position, the five-piece boy band arrived with a structural identity already built in: no conventional center, no designated face of the group. Every member is, by design, capable of leading from the front.

Debut & Formation

hrtz.wav emerged from *Still Heart Club*, an Mnet survival show that auditioned candidates by position. Each of the group's five members — Dane, Hagiwa, Keiten, Riaan, and YYJ — claimed the top spot in their individual category before being assembled as a unit. That origin story carries direct implications for how the group is structured and marketed: rather than a hierarchy of visibility, the lineup is presented as a collective of equals, each with the capacity to anchor a stage.

Their official debut arrived on April 8, 2026, and within the week they had already confirmed a festival stage appearance — an unusually active opening to a promotional cycle that signaled the group's intent to build a live presence early.

Music & Discography

The group's debut release, the six-track mini-album *The First Wave*, introduced hrtz.wav as a band with a stake in their own creative output. The title track is notably co-written by all five members, a collaborative approach to lyricism that, ahead of debut, the group cited as central to their artistic identity. The album's name — *The First Wave* — also functions as a statement of intent: the debut not as an arrival point, but as the opening movement of something longer.

Activities

Ahead of their debut, hrtz.wav spoke publicly about their ambition to become leaders in the global band scene, framing themselves within an international frame of reference rather than a domestic one. The confirmed festival booking within days of their debut date points to a promotions strategy oriented around live performance from the outset.
