This weekend's "Garden & Studio Tour" in Northampton provides an artful twist to a common event. In addition to seeing the fall gardens of well-known artists, visitors also get to see their studios. Among the participants is super-realist painter Scott Prior who is showing off a newly renovated studio and his three-level garden that winds down to the Connecticut River floodplain. Narrative painter Linda Post and her husband Geoffrey reworked their garden "rooms" after they were devastated in last October's snowstorm. She also gained a new ground-floor studio that opens into the gardens. At Ruth Folchman's garden Susan Barocas will create a plein air painting of the scene and center director Penny Burke's garden features Piper Foresco's metal sculptures. The self-guided tour of seven sites is Sunday (9/9), 1-5 p.m. $15 in advance, $20 day of tour. Benefits Northampton Center for the Arts, 17 South St. 413-584-7327.
