Tonight, and every Friday night from 5 to 9 p.m., the Portland Museum of Art is open free, courtesy of L.L. Bean. Inside is a topflight collection of American and impressionist masters and fine and decorative arts. Equally worth noting is the architecture: the award-winning Charles Shipman Payson building, designed by I. M. Pei and opened in 1983, the recently restored Federal-era McLellan House, and the beaux-arts L. D. M. Sweat Memorial Galleries, designed by noted Maine architect John Calvin Stevens. They’ve been ingeniously connected so that they flow from one to another.
**Don’t miss Backstage Pass: Rock& Roll Photography, which ends March 22. See my preview here.
