'Mix Nine' Lee Jae Joon X Chae Chang Hyun debuted as a three-man tray

Chae Chang-hyun, who appeared in 'Mix Nine', debuts. 

On October 10, Banana Culture Entertainment will release the teaser image of the new Boy Group TREI and will release the "Age & Key" soundtrack, which will be released in the form of a teaser before the official debut of TREI on the 17th. 

TREI is a three-member boy group composed of Lee Jae Joon, Chae Hyun Kim, and Jun Jo Tae. In 'Mix Nine', Lee Jae Joon and Kim Chang-hyun, who had been attracting attention due to their good visual skills and high-level talent, recruited Kim Jun-tae, who has a charming boy stone, and strengthened his vocal aspect. 

'Nai & Kee' is an impressive song with an easy hook that can be called up once and a killing point where the members directly participate. Chae Chang-hyun who rapping with a bass flow and Lee Jae-joon who is lightly chanting part and Kim Jun-tae's part with a lower voice crossed, and finished 'age & key' with 'TREI' only. 

According to his agency, TREI has released performance videos such as 'Easy', 'Just Yet' and 'X' from before the official debut. Through the Sound Cloud, I have released my own lyrics and compositions. In August of last year, she released "UP," an impressive voice and intense refrain, and has continued her musical activities
