Grimm Grimm

Grimm Grimm is the solo moniker of London-based, Japanese-born musician Koichi Yamanoha. Formerly a member of the psychedelic punk outfit Screaming Tea Party, Yamanoha pivoted toward a more intimate, experimental sound that he characterizes as 'space folk.'

His work is defined by a delicate marriage of traditional folk instrumentation, such as acoustic guitar and cello, with avant-garde electronic flourishes, tape loops, and Joe Meek-inspired production techniques. His career is marked by high-profile collaborations with members of Bo Ningen and Le Volume Courbe, positioning him within a specific niche of the London experimental scene that bridges psych-rock and neo-folk. Critically, he is praised for his ability to maintain a sense of pop melody while deconstructing song structures through atmospheric decay. His inclusion in the Hideo Kojima 'Death Stranding' ecosystem has expanded his cultural reach, aligning his sound with high-concept, melancholic sci-fi aesthetics. His discography explores themes of isolation, mortality, and cosmic wonder, often utilizing both English and Japanese lyrics to enhance the otherworldly, displaced quality of the music.
