Nacoco (나코코 / nacoco)
South Korean Masked Guitar Virtuoso, Songwriter & Leader of All-Female Rock Unit M4SK
Biography & Career Overview
Born June 3, 1998, in South Korea, Nacoco is a guitarist, composer, and digital creator known for her anonymous persona, performing in an enigmatic white theatrical mask. Picking up the electric guitar self-taught after being inspired by anime and rock music—learning entirely by ear and through video tutorials—she developed remarkable fretboard dexterity, aided by long fingers and high-speed motor control.
In April 2022, she launched her YouTube channel, quickly building an international audience that surpassed hundreds of thousands of subscribers through high-octane covers spanning classic heavy metal (Loudness, Gary Moore, Yngwie Malmsteen), J-rock/anime anthems, and modern shred. Operating under Reveal Entertainment, she transitioned from online viral phenomenon to live-stage sensation, headlining events like Seoul's No Mercy Fest and touring across Japan. Expanding her creative vision, she spearheaded the formation of the four-member all-female rock band M4SK, debuting original compositions that fuse hard rock, metal grooves, and melodic hooks.
