Pink business Is a Seoul-based ambient-noise band. Formed in 2015 with members consisting of Sung Sig Min(computer guitar, keyboard), Nahm Hyun(guitar, circuit bending inst.), Gay Gonjo(voice, bass), they experiment with the boundaries of music using distorted sounds and building them up with layers. They make an impression of improvisation with their sounds, but also compose specific scenes with sounds and tell them in a narrative.
