Heavenphetamine is a musical duo composed of Hiroki (keyboard/vocals) and Sara (drums/vocals).
Their distinctive style involves synchronising Sara's acoustic drums with Hiroki's synthesised sequences created through synthesisers and loop pedals, resulting in an electrifying fusion of electro-infused composition with a physical and punk-inspired edge, all achieved without the use of a metronome. Described as a blend of Krautrock and Post-Punk, their musicality strongly reflects the influence of Western indie music.
