Riaan

Riaan (리안) is the vocalist of hrtz.wav, the five-member band assembled through Mnet's Steal Heart Club and launched by Kakao Entertainment. He debuted on April 8, 2026 with the EP The First Wave, stepping into the role Kakao described most simply and most clearly: the voice of the band.

That tag is important because hrtz.wav is being positioned as a live band with youth-pop instincts, not an idol act borrowing instruments for styling. Riaan is central to making that framing believable. Kakao's rollout highlighted his wide vocal range and emotional delivery, while the debut material gives him space to carry the emotional pull that keeps the project from feeling purely conceptual.

On NINETEEN, the band's first title track, Riaan helps anchor the sense of nostalgia and open-ended youth that runs across The First Wave. He also took part in the creative process around the dreamy track Outta my mind, an early sign that his value to hrtz.wav may extend beyond lead-vocal duties into the group's longer-term writing identity.

As hrtz.wav expands from survival-show winners into an active festival and release act, Riaan sits at the center of the group's emotional language. That gives his rookie-era page unusual clarity. He is not just a frontman by position. He is one of the members most responsible for translating the band's concept into something listeners can actually feel.
