BTOB's Seo Eunkwang released his first full-length solo album "UNFOLD" on December 4, 2025, marking 13 years since his 2012 debut with the group. The 34-year-old vocalist delivers ten tracks exploring themes of self-discovery and emotional growth under BTOB Company.
Album Details and Creative Control
The title track "Greatest Moment" leads "UNFOLD," joined by "My Door," "Last Light," "When the Wind Touches," "Elsewhere," "Parachute," "Monster," "Love & Peace," "I'll Run to You," and "Glory."
Seo wrote lyrics for nine tracks and participated in composing or arranging most songs, with "Elsewhere" as the sole exception. This involvement represents significant artistic development for the vocalist, who previously contributed to BTOB releases including "Melody" from the group's "Beep Beep" mini-album.
The pre-release single "Last Light" dropped on October 29, 2025, building anticipation for the full project.
Concept and Themes
"UNFOLD" explores existential questions about life and identity. The album traces a journey from emptiness through pain, fear, courage, and liberation toward love and gratitude. "Greatest Moment" specifically addresses recovering fading memories and lost light, expressing longing for one's former self.
Vocal Performance Highlights
The title track showcases Seo's vocal range with warm tones, explosive high notes, and clear delivery. His performance reinforces his position as BTOB's main vocalist, combining technical skill with emotional resonance. The musical quality evokes theatrical productions, reflecting his experience in musicals including "Monte Cristo" and "Bachelor's Vegetable Store."
Music Video and Visuals
The "Greatest Moment" music video features calm yet mysterious cinematography with coastal and concrete settings. The visual treatment complements the song's introspective themes while highlighting Seo's matured tone and evolved performance style.
Sold-Out Concert Series
Seo will perform his first solo concert in over five years with the "My Page" series. Seoul shows on December 20-21 at Bluesquare SOL Travel Hall sold out immediately upon ticket release. A Busan performance follows on December 27 at KBS Hall.
On December 4 at 7 PM KST, BTOB Company hosted a YouTube live broadcast where Seo shared creation stories and interacted with fans.
Career Context
Born November 22, 1990, Seo debuted as BTOB's leader on March 21, 2012, with "Insane." After military service from August 2018 to April 2020, he released his first solo mini-album "FoRest: Entrance" in June 2020.
BTOB departed Cube Entertainment in November 2023 after 11 years. The members established BTOB Company in February 2024 for group and individual activities. "UNFOLD" marks Seo's first major release under the new label.
Beyond music, Seo has appeared on variety shows including "SNL Korea 5" and served as a judge on "Build Up: Vocal Boy Group Survival" in 2024. He briefly held a board director position at Cube Entertainment before the members' departure.
Reception and Impact
The immediate sellout of Seoul concert dates demonstrates Seo's strong fanbase and drawing power as a solo artist. The album's diverse musical spectrum-from emotional ballads to varied genres across B-sides-showcases his versatility beyond BTOB's group sound.
"UNFOLD" represents both a personal milestone for Seo and a statement of artistic independence under BTOB Company. The extensive creative involvement and thematic depth signal his evolution from idol vocalist to comprehensive solo artist capable of sustaining full-length projects.
