New Yorkers have recently benefitted from exhibitions of little-known (on these shores, at least) Italian artists whose work from the 1960s, ’70s, and ’80s is quite spectacular. First there was an exhibition at Casey Kaplan Gallery of folded and graphically treated paintings by Giorgio Griffa. (That’s one of them above.) Then there was the work in multiple mediums by Gianni Colombo, which was on view until the end of March at Greene Naftali. You can see pictures of that exhibition by clicking here.
