SF9 mark 10-year debut anniversary with second full album 'TENACITY', out on the 26th

SF9 are releasing their second regular album, TENACITY, on the 26th at 6 PM across music streaming platforms. The timing lines up with their 10th debut anniversary.

The title works on two levels. TENACITY means "perseverance, determination, and indomitable will." The embedded "TEN" nods to the group's ten years since debuting under FNC Entertainment in October 2016. The eight-member lineup — Youngbin, Inseong, Jaeyoon, Dawon, Juho, Yoo Taeyang, Hwiyoung, and Chanhee — has stayed active leading into this release.

March brought the special album About Love, a collection of ballads. Before that, Inseong released his first solo album, Crossfade:, in January and appeared on ENA's 아이돌 파견근무. Jaeyoon danced ballet for the first time in the creative dance-drama 나빌레라. Chanhee made his theater debut in the play Dead Poets Society. Youngbin, Hwiyoung, and Chanhee have remained steady hands in the group's album production.

(Ten years in and they're still collecting firsts.) Member involvement in production has defined their releases across the decade, and TENACITY reads as their fullest statement of that trajectory.
