Wikipedia:Articles for deletion/Neon Synthesis
It turns out that they have a media mention in a reliable source, Blabbermouth: https://www.blabbermouth.net/news/neon-synthesis-completes-work-on-debut-album/. Unfortunately a basic album announcement is not particularly |significant. Otherwise I can only find them at the |usual retail and streaming services. This WP article is old but the edit history shows that it started as a pretty obvious attempt at |promotion, by themselves or a fan back in 2007, with very little of substance added since
