The Pissarro dynasty aside, it's not often that you find more than one generation of artistic brilliance in the same family. The Palm Beach Institute of Contemporary Art took advantage of this art-world quirk last year with "The Smiths: Tony, Kiki, Seton," the first exhibition to encompass works by minimalist artist Tony Smith and two of his daughters. Dad was first an architect, then an art patron -- his collection included works by such abstract expressionists as Pollock and Rothko -- and finally an artist himself. The mathematical precision of architecture is prominent in Tony's works, including the huge The Keys to Given! (the title comes from James Joyce's Finnegans Wake), a large, black, steel sculpture you can actually walk through. It's too bad Tony didn't live long enough to see daughters Kiki and Seton hit their stride as artists. Kiki's fascination with the human body is evident in media as diverse as metal sculpture, ink drawing, and mixed media. The Paris-based Seton, in sharp contrast with both father and sister, works in photography, specifically large Cibachrome photographs that are, intentionally, ever-so-slightly out of focus. This beautifully assembled show, including more than 60 works created over the course of half a century, is a bracing reminder of the many ways artistic talent blossoms and flourishes.
