What you'll hear in the Fern Room is Abeyance by Haptic (Steven Hess, Joseph Clayton Mills, and Adam Sonderberg). Originally recorded in 2013, Abeyance has been reconfigured into a surround-sound installation that explores issues of spatial scale, temporal stasis, and the limits of awareness. Recordings of empty rooms—their near-silences magnified to reveal a hidden profusion of detail—are overlaid with one another and interwoven with the ambient sounds of the Fern Room to create a composition that, like the shifting light and atmosphere over the course of a day, unfolds almost imperceptibly in time. Subtle traces of electronics and distant piano melodies evoke indistinct presences and palpable absences.
