Yoo Young Jin has polished up the shiny pop sound of Korea's biggest musical names, helping them reach full star potential. He's been working with S.M. Entertainment acts since the ‘90s, burnishing the R&B sheen in S.E.S. and FLY TO THE SKY. Since then, he's engineered the whirlwind pop of Girls' Generation and the hard-hitting stadium sound of EXO-K.
