Unfortunately I can't tell too much about this album. Things I've gleaned from the suruga-ya page:
https://www.suruga-ya.jp/kaitori_detail/186141555
are that:
- The release year seems to be 1999
- The album title mentions anime, and so I've called this an Anime disc
- This album seems to predate all of EtlanZ's other known works
I also own a copy of the album, and do not recognize any of the music. Note I've added a tracklist with the track times. The cover shows 10 track names, but the disc actually has 11 tracks.
