Singer Kim Hee-jae is heightening anticipation ahead of his comeback with his third full album 'REVERB' by releasing additional concept photos.

On the 17th and 19th, Kim Hee-jae unveiled the third and fourth concept photos for 'REVERB' in sequence through his official social media accounts.

In the third photo, silver-toned outfits and a space decorated with a mirror ball combined with subtle light and reflections to create a mysterious and wistful atmosphere. In the fourth photo, a black leather jacket, a vintage backdrop, and a flashy patterned shirt came together harmoniously, while his deep gaze and relaxed pose expressed intensified masculinity.

The newly released concept photos carry a mood distinct from the previously revealed images, highlighting Kim Hee-jae's diverse charm.

The album title 'REVERB' means 'reverberation' and 'resonance.' Through this album, Kim Hee-jae plans to convey a deep musical resonance.

This album is his third full-length release in about two years and six months, following his second full album 'Hee-ro-ae-rak (Joys and Sorrows)' released in March 2024. Kim Hee-jae is set to meet audiences with deepened sensibility and an expanded musical spectrum.

Meanwhile, ahead of the comeback, various content including a timetable, preorder details, a mood board, and concept photos are being released sequentially. The third full album 'REVERB' is available for preorder in QR platform and album book versions, and will be released on September 7 at 6 p.m. through online music streaming sites.
