As others have stated, this is a departure from the normal uplifting Popol Vuh fare. It's a heavy, serious religious effort, and I would submit perhaps the beginning of what is now known as "Ritual Ambient". RYM describes the genre as thus "Ritual Ambient is a subgenre of Dark Ambient that focuses on dark, deep, disturbing, ritualistic and occult atmosphere. It often features some chanting voices, tribal rhythms and appropriate samples." OK, there are no samples, but otherwise that genre description would work as a review for this album. Popol Vuh was a pioneer in many fields, not surprising to find another one. The latter half of Side 2 is more positive like their mid 70s albums, but the overall effect is dark and mysterious.
My copy is the Spalax CD, which is just a basic jewel box reissue with no data or bonus tracks. I originally owned the Innovative Communications LP that I sold after obtaining the CD 20+ years ago, and as noted by others, is a 45 RPM which is entirely inconvenient. The cover is a single sleeve that has the IC layout aesthetic, and is nothing special.
