Joan Waltemath reviews two exhibitions by Jill Nathanson: Sacred Presence/Painterly Process at the Derfner Judaica Museum in Riverdale and No Blue Without Yellow at the Messineo Art Projects/Wyman Contemporary in Chelsea.  Waltemath writes: "Taking Genesis as a point of departure, Nathanson starts by using the debris from her studio floor, allowing her work to emerge from an essential chaos to create a series of freeform, sprawling mixed-media pieces. Nathanson uses gels, decorative paper, and adhesives in combination with poured acrylic paint to create the support structure of her pieces—a formal play that points to the creation of the earth in the text."
