There is something spectral about the abandoned structure parked in the middle of Glenn Horowitz Bookseller in East Hampton. Once erected in the woods in the no-man’s-land between Noyac and Bridgehampton, it was the temporary home of Adam Stennett in a self-created artist’s residency executed commando-style. Now, it is the centerpiece of an exhibition devoted to the work he produced there and the time he spent there called “Survival, Evasion and Escape (The Artist’s Studio).”
