Grimm Grimm is a musical project by London-based composer, recording artist, and producer Koichi Yamanoha, originally from West Tokyo, Japan. His music blends experimental pop elements with futuristic lyricism, weaving music box-like timeless melodies with ethereal soundscapes and electric textures.

Throughout his releases, Yamanoha has explored different nuances within his style. He incorporates a contemporary sound while drawing inspiration from baroque folk and 18th-century English 'infinite canons' forms, where repetitive patterns create an endless, cyclical feel. The melodies, often lingering at the end of his songs, echo like nursery rhymes—prayer-like motifs that invite listeners into a meditative, trance state.

Grimm Grimm has collaborated with a diverse range of artists, producers and labels —including ATP Recordings, Café Oto, Josephine Foster, Laetitia Sadier, Marta Salogni, Kevin Shields, Klein, and Hideo Kojima—through which his work has become firmly rooted in the experimental and avant-garde music scenes, as well as in the worlds of film and video game soundtracks.

With each release, his sound continues to evolve, drawing listeners deeper into a spiritual realm that resonates within the fabric of everyday life.
