Sprinting into Fall, September is filled with art, from The Armory Show, Armory OffSite and Armory week to The Poetry Festival, Feast of San Gennaro, Morningside Lights and the Gracie Square Outdoor Art Show. We’re looking forward to a new installation at the Doric C. Freedman Plaza by Public Art Fund, Celebrating PEN America’s 100 years of defending free expression in lights by Jenny Holzer at Rockefeller Center, and a spectacular exhibition, Hall des Lumières, at the historic 49 Chambers Street. The Met unveils its September facade niches, and we remember 9/11 + a plethora of thoughtful, beautifully curated gallery exhibitions, and even a $3 movie-day at a theater near you! Here are a few suggestions for September.
