The artist’s studio on Dock St., peeking from between the trees, resembles a weathered tower or lighthouse. Inside, large, playful paintings of expressionistic nudes, landscapes, and still-lifes — the pairing of a dancing violin and a vase against a background of deep blue was a common motif —cover the expansive walls, illuminated by skylights. The artist, Ulf Loven, who migrated from his native Sweden to attend school in New York City many years ago, is pointing out the charming townscapes inspired by his extended stays in Greece; others, depicting fields of vegetation in fruity colors and leafy palms, were inspired by his trips to Bali. Still others, more abstract, depict “a different kind of space,” as he puts it, by positioning rectangles of color in loosely brushed atmospheric like fields and otherwise playing with the viewer’s expectations and preconceptions, thereby garnering his or her participation. “I want to stimulate the viewer’s imagination and get intimate with them,” he said. The annual Saugerties Artists Studio Tour is an invaluable opportunity to experience people’s reaction to his work, which “is always interesting,” he added.
