Fourcolor is the artistic pseudonym of Keiichi Sugimoto, a Tokyo-based musician and sound artist known for his intricate and subtle electronic compositions. Sugimoto, who is also a member of several other musical projects including Minamo, Fonica, and FilFla, established Fourcolor as a solo venture through which he explores the delicate interplay between ambient textures and melodic fragments. Employing an array of digital and analog devices, his work under this moniker is characterized by the meticulous layering of processed guitar sounds, which he weaves together with electronic treatments and field recordings to create immersive sonic landscapes.

The album "Air Curtain" presents a further refinement of his sound, drawing listeners into a world where minimalistic melodies dance above a backdrop of lush static and dynamic aural hues. His work "Water Mirror" builds upon this foundation, interlacing melodic patterns with glistening sonic textures, encapsulating the reflective and fluid nature suggested by its title.
