It’s a strong month for art shows in and around Pioneer Square. An intriguing exhibit of 25 artists responding to the events of 9-11 is at Greg Kucera, part of their on-going series of museum-quality, theme shows. A nearby exhibit at James Harris features incisive colored pencil drawings by Geoffrey Chadsey based on photos downloaded from the Internet. Foster White showcases the cast bronzes, aluminum wall reliefs, and floating plastic ice cubes of sculptor Joseph McDonnell. In the midst of all this diverse activity, KUOW art critic, Gary Faigin, found several shows whose work has an interesting element in common. Here is his review.
