SF9 comeback August 26 with 2nd full album 'TENACITY', 10th-anniversary concert set for October

SF9 are back with their second regular album, TENACITY, out August 26. The 10-track release orbits themes of perseverance, determination, and indomitable will.

The title track is "Without Wings." Youngbin, Hwiyoung, and Chanhee all wrote lyrics across multiple songs. The album's concept has the group looking back at the past decade and pushing forward again—a natural move since SF9 debuted in October 2016, making TENACITY their 10th-anniversary statement.

The anniversary run doesn't stop at the album. SF9 will hold 2026 SF9 LIVE FANTASY #6 축몽(十年逐夢) at Seoul KBS Arena on October 10–11. The concert title translates to ten years of relentlessly chasing their dreams. Individual members have been chasing hard. Inseong put out his first solo album, Crossfade:, in January. Chanhee stepped onto a theatrical stage for the first time in Dead Poets Society. Jaeyoon took on ballet for the first time in the creative dance-drama Navillera.

Three members doing firsts in the same year as the group's 10th is a lot of momentum to walk into a comeback with. The full group now reunites under one release heading into a big fall.
