There's almost zero information about Hideaki Kobayashi's personally released albums (apparently VGMO's been able to get their mitts on a few), so I'm very interested in anything people might know about these beyond what's on Kobayashi's site.
Here's the discography:
Asterisk Didn't add this because I don't have a release year.
Technosphere Didn't add this because I don't have a release year.
Karen Didn't add this because I don't have a release year.
2001 release listed as not for sale. It doesn't appear that this album was ever distributed, but is rather BGM for the site. I therefore didn't add it, since we have a policy against adding albums that are only available via streaming players and aren't directly available for download.
