Brandon Williams’s review published on Letterboxd:
Far from perfect, but a cool alternative SF experience. Follows in the footsteps of Interstella 5555 with a bit of anti-music industry vibes. Of course the soundtrack is no Daft Punk music masterpiece, the stop-motion animation not nearly matching the hand-drawn aesthetics, and there's no guitar shaped spaceship.
It separates itself from other anime music films I've seen by focusing on a lesbian romance between a guitarist and singer. Pretty nice pieces on the soundtrack. Certainly not your average SF and worth a watch. If you have not seen Interstella 5555 though, consider it.
