For nearly 20 years, artists in TriBeCa have thrown open their studio doors to let people into their creative lives for a weekend. This year’s TriBeCa Open Artist Studio Tour kicks off early on Thursday night with a more traditional group show at the One Art Gallery space on Warren Street. Over the next four days, more than 70 artists will show their work in their own spaces—some sweetening the deal with free beverages and snacks. It’s a social as well as cultural experience, and you may even find some art bargains, too. Just be sure to wear comfortable shoes. For more information, visit toastartwalk.com.
