Subtle Inversion is an electronic music project consisting of Japanese Vocaloid Megurine Luka and American songwriter Gavin Goszka. Blending musical influences from both the East and West, the project’s music is a fun and energetic, yet lyrically insightful, blending of electronic, pop and rock elements.

The project’s debut album Kaleidoscope has the distinction of being one of the first (if not THE first) entirely original albums of English-language vocaloid music featuring Luka to be released in the United States.
