It’s hard to get a feel for just how wacky artist Julie Blackmon’s photographs are without seeing them in person. For Blackmon it’s all in the layered, loopy details that ping like electrified atoms around her action-packed photographs centered on little children run amok in her solo exhibition at Jackson Fine Art “Metaverse.” The featured players in her images are shirtless waifs with uncombed hair and sugar-dazed expressions. Her virtually feral children are long-limbed Norman Rockwell scamps but with some “Lord of the Flies” energy threatening to tip over from Americana into anarchy.
