The ailanthus is the tree that "grows in Brooklyn," a book you should read if you haven't yet. I improvised this piece for my performance as a "ghost flutist" for Introceptual Ghostland, a fantastical walking tour of the intersection of East Williamsburg/Bushwick/Maspeth on the Brooklyn-Queens border, masterminded by scrapworm, Henken Bean, and jo scari. I stood next to an especially lonely, but stalwart ailanthus on the corner of Bogart and Meadow, and listened to my sounds reflect off of a warehouse door. Then I actually remembered what I did long enough to write it down.
