David Dodd Lee's Sky Booths in the Breath Somewhere: the Ashbery erasure poems (BlazeVOX, 2010).

"Most of the poems I chose to erase came out of three books from A’s middle period--Hotel Lautreamont, And the Stars Were Shining, and Flow Chart," Lee explains in a very thorough interview here; he goes on: "I will say I wasn’t trying to ruin Ashbery’s originals—it felt to me like I was simply trying to take advantage of A’s genius (he’s got plenty to spare) and make something wholly separate seeming (stress here on the word 'seeming')."
