For many of us, even when we're not "on" the internet, we're still thinking through it; we see a nicely lit pattern of sidewalk impressions that we want to Instagram, or feel compelled to regularly dump our thoughts into either brief tweets or extensive Tumblr or Facebook posts. Whether we feel great or terrible or indifferent about the way the internet affects our experience of the world, we can't deny that the internet has also fostered a way for people to talk and form communities and collectives (especially within the visual arts) that contain multitudes and democratize the arts and their reach. A great example of this is the collective FAMILYFAMILYTREE, which began when a group of IRL friends in Boston started a blog, which later spread and amassed to include more artists from around the country. Then they started up a new site: a page that endlessly scrolls with images by multiple contributors—with no names, titles, or statements to interrupt your scrolling. In the collective's first exhibition in a physical place they introduce themselves with a "yes" manifesto, saying "yes" to "dissolving passive engagement. . . to absolving online persona and celebrity. . . to anonymity and collaboration," and so forth. The 25 artists in this show seem to refuse categorization or labels. They're a collective with many moving parts and, in a way, they mirror our interactions with the internet: boundless, flowing, mutable. Opening reception 7-10 p.m., exhibition open through Dec. 12, Gallery Four, 405 W. Franklin St., fourth floor, familyfamilytree.com, free.
