Holland Cotter finds all the bluster about controversial art at New York’s Drawing Center to be quite the tempest in a teapot. “In fact, the Drawing Center is noted for its rigorous formal, as opposed to ideological, mission. Since its founding in 1977, it has focused on two things: presenting museum-style shows of traditional drawing, whether in the hands of Rembrandt or Agnes Martin or 19th-century Shakers; and expanding, largely through contemporary art, the definition on what ‘drawing’ as a medium is.”
