K-pop Band hrtz.wav Debuts With ‘The First Wave’, Ushering In A New Generation Of Band Music

A new name is entering the global music scene as hrtz.wav officially debuts with its first mini album “The First Wave”, released on April 8, 2026, at 6 p.m. KST.

Backed by Kakao Entertainment, the five-member band is already being positioned as a fresh force in modern band music, combining technical skill with a clear artistic identity.

Formed through Mnet’s global survival program “Steal Heart Club”, the group consists of members who each ranked first in their respective positions.

This origin has shaped expectations around the group, as it brings together individual excellence into what many anticipate will be a strong collective sound.

According to The Chosun Daily, the group is being watched closely as a potential leader of a new wave in youth-driven band music, especially as live instrumentation gains renewed attention in the K-pop industry.

The lineup includes keyboardist Yoon Young-jun, vocalist Rian, bassist Dane, guitarist Kaiten, and drummer Hagiwa.

Each member brings a distinct musical style, contributing to a sound that is expected to balance individuality with cohesion.

hrtz.wav Members Shaping The Band And It’s Music

Yoon Young-jun anchors the group with structured and refined keyboard arrangements, while Rian leads with a versatile vocal tone capable of shifting between emotional and powerful delivery.

Dane’s bass lines add depth and rhythm, Kaiten’s guitar work introduces intensity shaped by his formal training, and Hagiwa’s dynamic drumming injects energy into the group’s performances.

Together, these elements form what fans and industry observers are already calling a “complete band synergy.”

Rather than relying on a single standout, hrtz.wav positions itself as a team where each role is essential to the overall sound.

The debut mini album “The First Wave” features six tracks, each reflecting a different aspect of the group’s musical identity.

The title track “NINETEEN” captures the energy and uncertainty of youth, setting the tone for the project.

Other tracks such as “Dream” and “Highlight” explore faster, emotionally driven themes, while “I AM SO FINE,” produced with hitmakers Galactika, adds a polished and contemporary edge.

“Eoribori,” co-composed by members Rian and Dane, offers a glimpse into the group’s creative involvement, signaling their potential as self-producing artists.

The closing track, “Our Story (Close To Me),” carries a more sentimental tone, focusing on the connection between the band and their fans as they begin this journey together.

As a whole, the album reflects both ambition and clarity. It introduces hrtz.wav not just as performers, but as artists with a defined concept and direction from the start.

Fans Respond To A Promising Debut

Even before their official debut, hrtz.wav signaled its global intentions. The group has already been confirmed as a performer at KCON JAPAN 2026, scheduled to take place from May 8 to 10  in China.

This early international stage highlights the confidence placed in the group by their agency and positions them as a band with global reach from the outset.

For a rookie act, this move suggests that hrtz.wav is not only targeting domestic success but also aiming to establish itself within the broader global music market. 

The release of “The First Wave” has been met with growing interest from fans, particularly those who followed the group’s formation through “Steal Heart Club”.

The debut represents the culmination of months of preparation, and early reactions point to excitement around both the music and the members’ chemistry.

With “The First Wave”, hrtz.wav enters the industry with a clear message and strong foundation.

Their combination of technical ability, creative input, and global ambition positions them as a group to watch in the evolving landscape of band music.

As they step onto both domestic and international stages, the group is not just introducing itself, it is setting the tone for what could become a defining presence in the next generation of music.
