Contributed by Jonathan Stevenson / “Personal Space,” the group show now up at Springs Projects, is especially impressive for the steady, uninflected confidence it reflects in art as a part of life, devoid of commercial pandering or sheepish self-doubt. Considerable credit for this virtue goes to Tommy White, co-founder of the gallery. As he hung the work, all made by his adult students from the Art Students’ League, and forged the show’s overall coherence, White consulted the artists to ensure that each individual voice was preserved. His curatorial hand is masterful, harmonizing seeming divergence and distinguishing apparent similarity. For a group show to sing, of course, the artists themselves need to possess a sufficiency of talent and heart. This gang does.
