The Peabody Essex Museum had a busy few days. On Thursday night, the museum hosted “La Vie Bohème,” an evening for Francophiles featuring French music, an absinthe tasting, and a lecture from New Yorker magazine writer Adam Gopnik, who spoke of his years living in Paris. Locals also sketched Heather Norcross (left), manager of Modern Millie Vintage & Consignments clothing in Salem, who dressed herself as a French model. The museum only got more crowded over the weekend when it opened “FreePort [No. 007]: Céleste Boursier-Mougenot ,” an installation featuring a flock of zebra finches playing amplified guitars. On Saturday, museumgoers waited for up to two hours to see — and hear — the birds.
