Curators William Powhida (the irascible Brooklyn artist) and Eric Trosko insist that this is a show, not an exhibition. The show asks: By what magic(k), by what disorganized religion, by what collective delusion, by what real transformation does a thing become a work of art? The artists included (a refreshing bunch of 16 from all over) are not referred to as artists; they're referred to as "operators." Among them are skeptics and believers both, "whose work acknowledges the gap between what is and what could be." Operators are standing by. (Platform Gallery, 114 Third Ave S, 323-2808. 11 am–5:30 pm, free. Opening reception Thurs July 1, 6–8 pm.)
