Although the biennial display of monumental sculpture along Sarasota’s bayfront has displayed works by area sculptors in past seasons, the sheer size of works by two local artists has brought more attention to their art. “It’s all about electricity,” a steel work that resembles a tree in the process of being struck by lightning, is by Richard Herzog, who teaches sculpture at New College of Florida. “Gateway,” a brushed aluminum piece that measures more than 8 feet tall and 16 feet wide, sits near the center of the 18 pieces on display between Selby Gardens and Gulf Stream and John Ringling boulevards, and is by Bradenton artist Linda Howard.
