Bushwick Open Studios returns for its 5th year and it’s the biggest yet, featuring over 375 shows of work by local artists and performers between Grand Street and Gates Avenue. Kick off the celebration at the launch party at 8pm on Friday at the Pine Box Rock Shop, or come on Saturday between 11am and 2pm for a mimosa and a map at Norte Maar (83 Wyckoff Avenue, #1B), then hit the streets; most shows are open from noon to 7. If past years are any indication, you are in store for an enormous art party, which will feature for the first time a pop-up biergarten in the newly-renovated Moore Street Market (110 Moore St.), brought to you by the sandwich masters at Farmcart (7 artists will also transform the market into a site of installations and performances). Of course, the MTA just announced the L Train won’t run this weekend, so plan an alt route; BOS has many options on its site.
