Bough and Niblock, what a pair.
Bough shot a ton of photos of Robert Wilson, the theater director, and his troupe. I also know there were some activities at Niblock's loft back then, which may or may not have been photographed by Phill (they're uncredited in the archives).
In retrospect I should have gone to his birthday parties; it felt weird to attend something where you don't personally know the celebrated individual, but I suppose that's how one meets other folks! At any rate, fascinating artist, and it's doubly cool to have walked the earth at the same time as someone of this stature.
