Glodia's first "original soundtrack", this Datam release contains original music from the FM-TOWNS version of the game. The sample quality of this version lies many feet above that of the PC-88, PC-98, X68000, MSX, SFC, and even PC-Engine version of the game (the SFC and PC-Engine versions used other, far inferior compositions though). The choice of tunes is also very good, this version includes the original Nobuhito Koise / Hiromi Okamura tunes, as well as a couple of later Tenpei Sato tunes. Abreath Nakamura arranged all the music, in exception of Sato's tunes, for this FM-TOWNS game, which most likely used redbook audio instead of sequenced.
Glodia Music Vol. 2: All Sounds of Vain Dream was released about a year after this one, it sounds just the same on the sample-side, as it was arranged , and partly composed, by Nakamura himself.
If I understand the booklet right, Datam / Glodia initially planned 5 "Goldia Music" releases:
Out of these, only the two first were released. Vain Dream II also saw a CD release, through Vain Dream II + Die Bahnwelt Full Arrange Version, and was released by Datam, it didn't have "Glodia Music Vol. 4" written anywhere. Zavas II never saw any soundtrack release, neither did that "Best Selection". It might be worth mentioned that Right Stuff got such a selection through Blue - Best of Right Stuff.
The disc says PSCX-1044, and the cover inserts says PSCR-5216.
