Brooklyn’s thriving artistic communities will be celebrating the 14th annual Armory Arts Week with exhibitions and events boroughwide on Saturday. The iPhone app, The Art and Absinthe Guide to Brooklyn, will help you locate each participant (and drink specials at bars like Huckleberry), but the day’s highlights include an all-day open studio at Cobble Hill’s Invisible Dog, culminating in an opening reception to kick off the gallery’s four new exhibitions starting at 6pm. North Brooklyn will be filled with even more parties and spectacles, all under the umbrella of Brooklyn Armory Night. In Williamsburg, Like the Spice opens its month-long, semi-satirical version of an art fair, titled “Art’s Not Fair,” and video projections will be installed throughout the neighborhood. There are also two art strolls–Greenpointers has organized a tour of 30+ galleries and alternative spaces (not just in Greenpoint), followed by an afterparty at TBD at 9pm. And in Bushwick, the biannual Beat Night (deemed the Best Neighborhood-Wide Gallery Night by L Magazine) returns with an art walk/bar crawl through a varied group of independent galleries and art spaces that will be open from 6-10pm, with English Kills welcoming revelers afterward. Luhring Augustine, the first Chelsea gallery to open up in the hood, is not on the list, but it’s worth a visit before 6pm to see its inaugural show of Charles Atlas’s video installations.
