Lee Hyun Do, a former star rapper both with ‘90s outfit Deux and on his own, now adds mellow vibes to contemporary K-pop. Bringing a laidback sensibility to outfits who normally charge headlong into their music, Lee pens sparse acoustic guitar-focused pop for MYNAME and funkier synth-pop for INFINITE H. He's also lent rappers like DinDin songs that move at a relaxed tempo perfect for highlighting their MC abilities.
