On Roomic Cube, musician Takako Minekawa has a deliberate tunnel vision in the counterbalance of the cheerfully buoyant and accompanying comedown. Prior to later collaborations with artists like Jim O’Rourke and guitarist Dustin Wong, Minekawa shared the retrofuturistic “Shibuya-kei” spotlight with like-minded nineties contemporaries like Cornelius and Kahimi Karie. Moving in a cosmic headspace that balances subtle melodicism and electroacoustics with downright playful lyrical repetition, the album’s accomplished sound collage is as much a reflection of the canonical microgenre as any other.
