In 1981 Liverpool's Orchestral Manoeuvres in the Dark released their third album. Which became their worldwide breakthrough. The title was named after the 1977 book "Morality and Architecture" by David Watkin. The album was making use of the mellotron, a mechanical tape-replay keyboard that was much used in progressive rock in the early 70's. The LP cover was with a cut-out to display the image of the inner cover. This was never restored on CD editions.

 The album holds 3 singles and synthesized sounds, electrical Gregorian chant and even choral singing. Starting with the cold war theme of  "The New Stone Age". "Georgia" is song about a city after being destroyed by bombs which is paving the way for the kind of songs we can hear on their next album "Dazzle Ships". The title song is the least interesting being an instrumental filler. Two songs are inspired by Jeanne d'Arc (Joan of Arc), the hero of France during the Hundred Years' War.
