After releasing the music videos for debut title track “Rocking Girl” and for the second track “Bye Bye Bye” last month, rookie group 4K is back with another music video for latest song, “Moonlight Sonata”.

“Moonlight Sonata” features refreshing and sweet piano music accompanied by lovely vocals of the members, that capture the hearts of the fans who are tired of electro-upbeat sounds.

4K is under Choeun Entertainment and is comprised of members Cory, Sungoh, Kisu and Seokjun. Going against the mainstream, the group focuses on its own unique acoustic pop sound.
