Contributed by Brett Levine / “A nonobjective idiom; unexpected surfaces; a synthesis of primary structures with surrealism.” That’s Lucy Lippard, in 1966, writing on the group sculpture show “Eccentric Abstraction” at the Fischbach Gallery in New York. Robert Pincus-Witten wouldn’t coin the term post-Minimalism until five years later, but that idea tracked with Lippard’s description and is arguably the strongest conceptual foundation for Sara Garden Armstrong’s “Environment: Structure/Sound III.” First exhibited in 1979, this 2024 incarnation at the Alabama Center for Architecture is a poignant reanimation and re-imagination of post-Minimalism as a practice. Accompanying the work are contextualizing process sketches, the original score, and new risograph prints.
