Richard Serra, “Forged Rounds”

No one does heavy metal heavier than Richard Serra, who is presenting three new bodies of work at as many Gagosian locations. Uptown, the gallery’s Madison Avenue space features a new set of Serra’s monochrome drawings made by pressing oversize sheets of paper into thick layers of black pigment. Gagosian’s W 21st venue is taken up by one of the artist’s signature installations of curving Corten plates. But the work that arguably outweighs them all is his “Forged Rounds” series at the Gagosian flagship on W 24th Street. Comprising arrangements of massive drums fabricated from solid steel, each sculpture tips the scale at exactly 50 tons, though they vary in height and diameter, offering a kind of monumental object lesson in the meaning of mass.
