An uncompromising group show of two expat Russian artists of the Perestroika generation, this treat at Fridman Gallery is as notable for the diamond-sharp artworks in it as for the scenographic setting in which they are displayed. First, the art: Neo-Constructivist paintings and drawings by Anton Ginzburg, employing hard-edged geometries to open up imaginary dimensions and landscapes, plus a mesmerizing video of Uzbek men hand-counting one million Uzbekistani Soms (about $400) in the basement; and free-hanging paintings on linen and Mylar by Dasha Shishkin, featuring semi-abstracted naked figures who smoke cigarettes and drip strange substances into one another's orifices. As for the setting, Ginzburg has deployed his strict geometries to painting color blocks on the gallery's walls (including one large, bold, brown square), creating dazzling lines of sight as one traverses the gallery and fusing the disparate works into a single expression.
