Resonance–visual, musical, thematic–characterizes Darkwater Revival: After Terry Adkins, the current exhibition at the Arthur Ross Gallery. Conceived as an homage to the late revered University of Pennsylvania professor, who died tragically of a heart attack in 2014, the show contains work by Adkins as well as eleven young artists who trained with him. Adkins’ absence haunts the exhibition, but his presence is felt in each work.
