Citadel's Blood on the Sun is essentially two albums in one. The first consists of a cleaned-up historical recording of composer
Miklós Rózsa taking a studio orchestra through the score of the 1945 film indicated in the title, and the second made up of latter-day adaptations of
Rózsa's film themes for chamber combinations and, at the end, chorus and organ. The common thread in the adaptations is that
Rózsa himself had a hand in preparing and recording them, with the assistance of producer
Tony Thomas; all of this extra material has not been available in a long time, and some of it has never appeared on CD before.
