Tony Feher has been skillfully manipulating found and cast-off materials—plastic bottles, Styrofoam, beverage crates, etc.—into poetically arranged sculptural installations for 25 years. “Encore” includes two shelves lined with plastic or glass bottles filled with different concentrations of blue food coloring, a series of wood planks studded with colorful glassware, and a curtain made up of strands of blue and orange PVC tubing strung on rope.
