Y2K
The male trio Y2K successfully delivered its reunion concert.

Y2K took the stage last month at the “2025 BUSAN INTERNATIONAL ROCK FESTIVAL”. The group set the atmosphere on fire from the opening with “Bad”, recently performed at the “KOREA-JAPAN TOP TEN SHOW”, then followed up with “괜찮아” (it’s okay) and “Why?”.
They then captivated the audience with the ballads “내안의 너“ (you in me), “깊은 슬픔“ (deep sorrow), and “Hidden”, prompting a collective sing-along. The highlight arrived with their biggest hit, “헤어진 후에“ (after the breakup), followed by “First love (à Adonis)”, dedicated directly to fans, creating a deeply emotional moment.
This concert at the “BUSAN INTERNATIONAL ROCK FESTIVAL” marked the first full reunion of members KO JAE GEUN, MATSUO YUICHI, and MATSUO KOJI after 23 years, generating huge anticipation even before the event. On stage, Y2K turned the festival into a shared emotional experience and announced the full return of their group activities.
Additionally, through their official social media channels, Y2K hinted at preparing a solo concert titled “Y2K STILL RISING EVER-EVOLVING LIVE”, further fueling fan excitement. This show promises to reveal the group’s maturity and evolution after 23 years of silence. Details will be shared later via their official channels.
Rockin Korea stated:
“We sincerely thank the audience for the warm welcome given to Y2K during this concert, organized after so many years. The upcoming concert will be prepared wholeheartedly by the artists and team to return, through memories, the love fans have waited for so long. Please look forward to it.”
