For the past five years Randy Twaddle has investigated alternative mediums in which to render the power lines and transformers that have captivated him throughout his career. This has included hand-knotted wool rugs and tapestries, textiles and wall coverings. For this exhibition, Twaddle has returned to his original medium of choice, charcoal on paper, to create two intricate and precise large drawings that appear to be abstract, though photography-based.

Twaddle will also be showing for the first time in his 30-year career a group of recent small collages created from printed source photographs he has taken of power and utility lines. In these collages, the various utility lines, the sky, clouds and tree branches are cropped and rearranged to create abstractions in blue, black and gray with an occasional additional area of color created from coffee-stained paper.

Twaddle will also exhibit three-dimensional work, a grouping of identical bas-relief tiles cast in hydro-stone. These tiles were created by manipulating a digital image of a two-dimensional, transformer-based pattern into virtual three- dimensions, printing a 3D model of the tile, using the 3D model to create the casting mold, and then casting in hydro-stone, a strong gypsum cement.

On view through April 20.
