I like your translations, zimmo. The construction / destruction and innocence / violence is a certainty. And transformation, indeed leads back to the Angel Man.
One man is called the Angel Man.......he believed he was an angel and said, 'I was exactly who I was up until the 5th of February. 1948. And then I became an angel ... it was just after lunch.' And from that point, he believes that his old person disappeared and his angel took over him. He was totally reborn at that moment. - David Bowie on meeting Outsider Artists.
One minor point is the lyric "souring" which I think is "soaring", as in soaring buildings. The daily life of an architect driven by man's obsession to accomplish the tallest building in the world. As noted by power2charm, this was thwarted by God at Babel. Bowie describes Outside as a "perversion of catholic ritual", "a relish of pagan attitudes" and "driven by a pagan engine". It's not Eden but it's no sham. There is no hell and there is no sham.
Bowie also mentions "some kind of blood letting and possibly an unconscious effort to cleanse our souls before the end of the millennium"...."Something in our blood. Something in our skies. Oh Ramona, if there was only some kind of future"
Till there was rock, you only had god
