One tap, then another, then a rapid-fire sequence. Silence, interrupted by a sudden chorus of clicks and clacks. The sounds emerge from a row of mysterious metal objects, with no evident human volition. Yet there’s a sense of urgency in this indecipherable conversation, a message trying to get through.
This is Matthew Ostrowski’s “Summerland,” on view at the Albany Museum of History and Art through Jan. 3. A sound installation designed for 24 antique telegraph sounders, the piece is inspired by the overlap of science and spiritualism during the mid-19th century.
