Added, for the sake of completeness, Symphonic Suite: 4.6 Billion Year Story ~ The Theory of Evolution. This album is a synth arrangement of the music from the NEC PC-98 game, whereas the other album with a similar name posted previously here is from the SNES/Super Famicom music.
These 4.6 Billion Year albums haven't really caught my attention in the past, but having listened to more Koichi Sugiyama, it's interesting to hear the two very different styles of the the composers involved. For example, track fourteen (japanese title) is very exemplary of the Takenouchi Style, whereas track seventeen is very much Sugiyama. I hope you enjoy it, and thanks again to Acid Beast for this one.
