Two Ridgefield artists - Frances B. Ashforth and Chris Perry - are included in this Sunday's Silvermine Gallery new members show. Ashforth's prints and paintings are meditations on the horizon line and the possibilities of immense open space. Perry's book-art sculptures channel the whimsical and the architectural, while sometimes having an almost animal presence. The reception, from 2 to 4, is open to all. The gallery, at 1037 Silvermine Road in New Canaan, is open afternoons Wednesday through Sunday.
