It’s a refreshing idea, to name an exhibit “Juice Bar” in the dead of winter. The thought conjures warm climes and healthy beverages — and maybe even a bracing cleanse after holiday indulgence. What it means in the case of BigTown Gallery in Rochester is an eclectic group exhibit featuring gallery regulars along with some new faces — or rather, their works. These include witty and meticulously crafted sculptures of found materials by Jessica Straus, quirky carvings by Richard E. Smith, and fantastical pen-and-ink drawings by Rick Skogsberg. Pictured here: a chromogenic photographic print by Virginia Beahan and Laura McPhee titled “Galaxy of Orchids.” In celebration of BigTown’s 10th year, all are on view through April 5.
