As spring melts into summer here in Bushwick, we are greeted with sidewalk barbecues, doggy ice cream, and fresh roster of live music performances. If you’re going gallery hopping on one of these blazing afternoons, check out “SPF 32,” a group exhibition curated by independent curator, Madeleine Mermall, at the William Ulmer Brewery. Opening on June 15, 32 emerging and mid-career artists celebrate the onset of summer’s familiar feelings of freedom (both sexual and otherwise) tempered by melancholy through vivid, chromatic, neo-realist paintings.
