YONKERS, NY.- We cannot touch or hold it, but we can see it, and with it, see our world. Light defines our physical, visual and mental experiences. It determines how we move and stirs our emotions. Opening on February 1 at the Hudson River Museum, The Magic of Light will examine light art as physical sensation. Magic presents work by 14 artists who changed the nature of art by using light rather than paint or stone to create. Their artworks move away from the traditional art object and focus, instead, on the viewer's perceptions. The Magic of Light displays the work of both established and emerging American artists. James Turrell, part of the Light-and-Space movement of the 1960s and 1970s along with Robert Irwin, works with pure light, while his main goal is the viewer's highest visual and physiological perception. Magic also shows how the vocabulary of these seminal artists is reexamined by the recent work of artists like Susan Chorpenning. Her work, Backtrack, presents a shifting reality, her changing images held in phosphorescence. The entire museum is the framework for this exhibition. Five new installations by Stephen Antonakos, Pietro Costa, Kenny Greenberg, Erwin Redl and Robert Thurmer were created especially for The Magic of Light. They respond to the unusual spaces and varied architecture in and around the museum's complex of galleries, courtyards and the historic Glenview Mansion. For example, the thousands of lights in Erwin Redl's Matrix I cover the 100-foot south wall of the Museum's main gallery. Exhibiting artists are Stephen Antonakos, Dan Flavin, Susan Chorpenning, Pietro Costa, Felix Gonzalez-Torres, Kenny Greenberg, Robert Irwin, Bill Jones and Ben Neill, Sheila Moss, Liz Phillips, James Turrell, Erwin Redl, Keith Sonnier and Robert Thurmer.
