Gagosian presents the work of legendary sculptor Michael Heizer. Heizer's first exhibition with the gallery comprises rarely or never-before-seen early paintings, the Altar series of new monumental steel sculptures, and negative wall sculptures featuring metamorphic and igneous rocks. Working largely outside the confines of gallery and museum, Heizer has redefined sculpture in terms of size, mass, gesture, and process. In the late 1960s, he relocated to New York, while continuing to travel and live in the open terrain of the American West, where he has since created awe-inspiring land artworks. Michael Heizer 'Altars' will be on view until July 9, 2015 at Gagosian Gallery, 555 West 24th Street, New York. photographs by Eric Minh Swenson
