LEE SANG, JE UP
More than just a vlog, the latest video on the IDEAL VOICE channel takes us behind the scenes of JE UP’s concert, where LEE SANG lent his voice for a moment of pure nostalgia and intact camaraderie.
The emotion was palpable in Hongdae. To kick off 2026, LEE SANG shared a special video with his community capturing his on-stage reunion with his former IMFACT bandmate, JE UP. Between rehearsals and a shared meal in the dressing room, the two artists used this vlog to openly discuss their journey, maturity, and evolving relationship with fans.
One of the most memorable moments of the video was their discussion about the longevity of their career. JE UP, with a hint of nostalgia, noted the passing of time:
“It’s been 10 years since our debut. 10 years is an immense amount of time, the time it takes for mountains to change their faces”.
This reflection led to a deeper discussion about the image they once projected. JE UP revealed that he wished he had “let go” sooner, explaining that during their group years he often had to “keep up appearances” and follow strict rules about what he could say or not. Today, he feels freer, asserting strongly:
“At this age, I don’t want to live worrying about all that… I want to live my life, do what I want, and enjoy it”.
On the musical side, fans were treated. LEE SANG and JE UP performed together songs full of memories, including “애간장”, a track from the soundtrack of a drama in which LEE SANG had acted and IMFACT had sung at the time. LEE SANG amusingly noted that they had almost never performed this song live during their group activities, making this performance at JE UP’s concert even more precious for long-time fans.

The vlog ended on a positive note after successful rehearsals of songs like “Perfect” by Ed Sheeran and “Too painful love was not love” by Kim Kwang Seok. LEE SANG concluded by emphasizing that despite years apart due to military service and solo careers, their “chemistry” and vocal synchronization returned instantly.
These reunions are not just a gift for the ears but proof that the bonds formed within IMFACT remain unbreakable, no matter the paths taken.
Between laughter, confidences, and perfect harmonies, LEE SANG and JE UP demonstrated that true artistic friendship knows no expiration date.
