The work revolves around a bizarre history rich of visionary symbolism, dealing with an apocalyptic end of Earth, full of Biblical and mythological visions. Authors like Henry Miller and Baudelaire has been cited as inspiration for the lyrics. The album is introduced by a long voice declamation ("Soon you'll be aboard a tramway..."). After several minutes the music evolves gradually into a full sway with what would have a been a single suite if not to the technical limits of old LPs. The music sometimes resembles Gentle Giant or ELP's one. It includes passages of total improvisation.
