Featured Review: Philadelphia Wireman In the dense core of these tautly wound sculptures of wire and detritus lurk bits of crumpled McDonald's and Tastykake wrappers, nails, bolts, tape, a Christmas ornament, batteries, a single penny, a knot of thread and a charm that spells "star." The small pieces exude a kind of maniacal dedication to their self-authored craft — part-scavenging, part-bundling, fastidiously circled innumerable times with rounds of wire. Displayed upright like petite figures, they appear tribal, fetishistic or like reliquaries to the toss-away stuff of dailiness. Found on trash day in a Philadelphia alley in 1982, these anonymously made pieces — numbering 1,200 in total (20 are exhibited here) — deny all common senses of purpose, pleasure and nameable source. Rather, they're all immediacy and earnestness — the material manifestation of the mysterious compulsion that made them. Through April 31 at William Shearburn Gallery, 4735 McPherson Avenue; 314-367-8020 or www.shearburngallery.com. Hours: 10 a.m.-5 p.m. Tue.-Sat.
