I’ve never had more trouble with a title. The connection of the trumpet with the vulgar and fatalistic/nihilistic text raised to an angel of the Apocalypse is irresistible. But what title would dellight while making that connection? Finding one was torture

Here were some: Post Christian Apocalypse? Apocalypse Now (Rev. 8-10) The Final Whimper. So Gentlemen, Is This How it Ends?

My favorite was The Final Whimper, but my wife said people would not understand it (not you, of course, my dear friends.) That required connecting The Waste Land and Rev: 8-10.

The current title is friendly to people who are not all that familiar with the Apocalypse in literature.  And for those who are, messenger means angel.
