M To M consists of three male members with different style of vocal which blend well together.
Under MNet management, they debuted in 2004 with the soundtrack album for the drama title ‘Tell Me That You Love Me,’ with the same title.
Originally M To M consisted of only two people, Kim Jin-ho (김진호) and Son Joon-hyuk (손준혁). However for their second album, Kim Jin-ho left for SG WannaBe and M To M was re-built with two new voices, Choi Jung-hwan (최정환) and Kim Sung-tae (김성태). Jin-ho is still featured in some songs.
As member of MNet’s Big4, they gained less attention than other groups but still continue to make good ballad music with their talented voices.
