I always ask myself Why did they ruin this LP of majestical space-imaginings with some cack-handed illustration of a 'cosmic crack'?! Just get a photo of the lunar surface, get somebody to airbrush some ziggurats on there and maybe a spaceship or 2 with rainbow exhausts. Job done.
Or just turn the gatefold inside out and use this as the cover.
Intense Synthi workout culminating in epic Egyptian holiday-rock.
