hrtz.wav return 5 months after debut with 'The Second Wave : MOMENTUM', featuring RIIZE's Seongchan
hrtz.wav drops a 6-track mini album on September 9, with title track 'ALIVE' featuring RIIZE's Seongchan, capping a debut run across 10 festivals.
Five months in, already on their second era
hrtz.wav (하츠웨이브) are coming back. The global band's second mini album, The Second Wave : MOMENTUM, drops September 9, roughly five months after their debut.
The six-track project leads with ALIVE, which features Seongchan of RIIZE. The full tracklist:
- ALIVE (Feat. Seongchan of RIIZE)
- Mind
- Sunday Morning
- Play My Guitar
- Thinkin' Bout You
- First Daylight
Ten festivals before album two
The comeback lands after a debut stretch that would exhaust most new acts. hrtz.wav have already played 10 domestic and international festivals since debuting: 2026 Awesome Music Festival, KCON JAPAN 2026, 2026 Seoul Park Music Festival, 2026 Busan One Asia Festival, 2026 Palette Festival, Soundberry Festa 26, and JUMF 2026 Jeonju Ultimate Music Festival.
Three more festival slots are locked in. Sound Planet Festival in September. XMF and NOL Festival in October. Most groups don't hit that calendar until year two or three. The album arrives right in the middle of the run, which means the live momentum feeds directly into the release cycle.
