‘Festone’ (festoon) feels like the perfect title for this festive, beautifully colored acrylic painting by Turin-based painter Giorgio Griffa. Hurricane Sandy damaged the delicate-appearing work in his first New York solo show since 1970 in October; now the prolific Griffa, who folds and shelves his paintings upon completion, is back with a new selection of pleasingly minimal abstractions worth celebrating. (At Chelsea’s Casey Kaplan Gallery through March 2nd).
