"Julie Mehretu: Liminal Squared"

Mehretu has built a major rep thanks to elegantly dynamic abstractions that spin building plans and other architectural documents into schematic tornadoes of whirling lines and diagrammatic fragments. Her content sources supposedly provide some sort of social import to her paintings, but it's best not to bother with any of that, and concentrate instead on the buzzy effects of her compositional skeins. This show marks her debut with the powerhouse midtown gallery.
