'Terrestrials.' Austin photographer David Johndrow found inspiration in his garden for his latest body of black-and-white images. Says Johndrow: 'My garden (is) where the most interesting things happen on a very small scale; things that at first glance appear quite ordinary, but turn out to be, on closer inspection, sublimely beautiful.' Opening reception is 6 to 8 p.m. Saturday. Exhibit continues through April 10. L. Nowlin Gallery, 1202 W. Sixth St. Free. 626-9301 www.lnowlingallery.com .
'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. www.womenandtheirwork.org .
