Von Bartha presents two solo exhibitions by New York- based artists Sarah Oppenheimer and Olaf Breuning, currently on view through July 30. Oppenheimer’s “N-02” invokes Bartha’s deep-rooted engagement with kinetic artwork. Known for the manipulation of the built environment, the artist presents three interconnected “instruments,” each composed of an elongated black aluminum bar and two linear lighting tracks. Arrayed across the ceiling, lamps weave between gallery walls. Visitors are invited to manipulate each instrument. The energy of human motion intertwines with the frequencies of the environment. Breuning’s second solo exhibition at von Bartha, “Two Lakes,” consists of several large, tactile paintings placed in dialogue with three stone sculptures. Known for his humorous approach, the artist playfully addresses pressing subject matters such as global warming, and environmental disruption. The works are inspired by Breuning’s surroundings in upstate New York, encompassing trees, raindrops, flora and fauna.
