Matters of the spirit underlie Christina Hirsch’s new series of expressionistic landscapes inspired by the banks of the Hudson River. They articulate a certain urgency. Some bear a sense of the Gothic. Others possess a subtle but intense emotional timbre checked by deserts of meditative minimalism. Winds ply the grasses and clouds, acknowledging the constancy of change. Nature and spirit share a restless passion in these paintings and move toward an unseen moment beyond the paper’s edge. This series of works reinterprets landscape painting in a boldly fundamental palette evocative of transformative intersections between nature and the human psyche. At Gallery 135, 135 Warren Street.
