Ryan Sullivan’s abstractions invite viewers on a process of discovery in new work at 125 Newbury; what appear to be relatively straightforward non-representational paintings are in fact complicated images created by both chance and forethought. Sullivan’s working technique is key. Using pigment suspended in industrial grade resin, the artist makes the paintings ‘backward,’ by laying down the marks that will be seen on the surface, then continuing to add on the background layers, eventually moving the piece from its frame once set. As much sculpture as painting, the untitled pieces foreground our own exploration of how to interpret what we’re encountering in each dynamic and complex composition. (On view in Tribeca through Jan 28th).
