An image album based on Kazumasa Hirai's science fiction novel "Shingenma Taisen" and one of the representative works by Sense of Wonder led by Hiroyuki Namba. A masterpiece shining brilliantly in the history of Japanese progressive rock, expressing a grand story that transcends time and space through music, is finally released in a cardboard sleeve jacket edition! Other image albums based on science fiction novels produced by Sense of Wonder during the same period include "Green Requiem" (original work by Motoko Arai), released in 1984, and "Kujira ga Ginga Network de Uta wo Utatta" (original work by Mariko Ohara), released in 1985, both of which were released on cardboard sleeve CD, but this work, which shows the strongest progressive rock style, had long been awaited for a cardboard sleeve release. For Sense of Wonder, whose activities were mostly as a keyboard trio, this is the only work from the twin-keyboard four-member period featuring Rei Atsumi (then credited as Rei Atsumi), who led progressive bands such as Moondancer and Tachyon and later became active as a member of VOW WOW. 2026 remaster. Originally released in 1984. Comes with commentary / liner notes by Hiroyuki Namba. Cardboard sleeve jacket specification reproducing the original record as faithfully as possible.
