The joint concert, 'Boys to Man', is a play off of the name of the talented group, Boyz II Men, and much like the title, the concert will show the singers' maturity.

BTOB will represent those in their early 20s, 2AM will sing songs that are relevant to those in their mid-20s, and K.Will is taking on the more mature crowd in their early 30s. 

The concert production company stated, "We will show how a boy grows up to become a man, and turns his dreams as a child into a reality. We want to lift the hearts of the youth of this generation."

Each group will perform a mini-concert of 7-8 tracks, and flower boy actor Dong Hyun Bae will be the storyteller for the concert. 

Music listeners won't want to miss this joint concert on June 29 at Kyunghee University!
