'Treading Where No One Hears The Echo of Her Foot Fall.' Houston-based artist Kathryn Kelley up-cycles and reanimates objects of urban refuse into large, fleshy sculptures that often stand in the place of the self. The impressive scale of these pieces creates a theatrical position for viewers who are confronted with gregarious forms, or intimations of the shadowed self. Remnant inner tubes, doors, frames and windows morph and mingle in these ambitious works. Opening reception is 7 to 9 p.m. Saturday. Exhibit continues through April 15. Women & Their Work, 1710 Lavaca St. Free. .
