Tokyo's Opera City Art Gallery has taken a novel approach with its summer show: Instead of the usual one-man or themed group exhibition, it is running a couple of concurrent but totally unrelated one-man shows at its Shinjuku exhibition space.

One admission price will get you in to see both (as well as the permanent collection and Project N spaces upstairs), but the two shows have distinct titles and catalogs and are running in different areas of the big Opera City space. I believe this is the first time the gallery has done this, and it actually works rather well. Although the two artists are from the same generation, their approaches are worlds apart.

The larger of the shows is "Plots Laid Thick," by 45-year-old American artist Raymond Pettibon. This is a very diverse exhibition, with hundreds of drawings, several videos, a collection of album covers, and a few paintings and other works also tossed into the mix.
