U-KISS former member Allen Kibum has released his first solo album today.

Today, he released his first solo song, "Longing" on various music sites. The song also features Ha Ri Su.

An official commented, "After leaving U-KISS, he has worked hard music-wise for 2 years in Japan. It is time for him to release an album and be recognized for his hard work. Ha Ri Su also has been working on musicals as well. We chose to work with Ha Ri Su because the vocals for this song would be hard for a normal female vocalist."

This song will have a hip hop sound and will be different from his usual style.

Allen Kibum commented, "Now that I have new music and a new name, I want to be reevaluated by the fans."

After the release of his new album today, he will perform in Korea until May.
