Grimm Grimm is the space-folk solo project of Koichi Yamanoha, a London-based Tokyo native and former 1/3 of cult psychedelic punks Screaming Tea Party. With Yamanoha as the lynch pin, Grimm Grimm features a shifting line-up of collaborators that includes Le Volume Courbe and Bo Ningen. Packed with hooks, the Grimm Grimm sound mixes the melancholic beauty and noise of Nico, the sound scape of Eno and the melodies of The Beatles with baroque flourishes and a passing nod the otherworldly pop sensibility of Joe Meek.
