war | machine is an exercise in the work of memory, the ecology of photographs—and an exploration of the destruction we wage against one another and our world. It is poetry that is meant to be updated, reordered, and continuously rediscovered. It is an invitation to the songs of ghosts and the shimmering of the aurora borealis as a bomber flies over the Arctic on its mission to make still more ghosts by unleashing the fires of heaven on the earth below.
