It is always great to be contacted by a fellow fan, especially when it is for a band who are no longer active plus who are not that popular outside of Japan. With the help from James I was able to add more info and releases (sans scans at the moment) to the Miscellaneous section of メトロノーム. I think that you can now find a fairly accurate overview over there though any info or corrections are still welcome! There are also a number of singles in the mail coming over from Japan, meaning I will start work on the Singles section anytime soon.
