And Jonathan Lethem writes about his evolving view of the artist.

This week in the magazine, Peter Schjeldahl reviews “Regarding Warhol: Sixty Artists, Fifty Years” at the Metropolitan Museum of Art, a show that juxtaposes examples of Warhol’s paintings, films, and sculpture with works by sixty other artists who were influenced by his legacy. ”The sixty artists are well chosen but, in truth, too few. For or against, what artist of the past half century hasn’t reacted to Warhol’s reduction of art’s once sacred aura to a cult of the obvious?” Schjeldahl writes.

In this audio slide show, Schjeldahl remembers seeing “Cow Wallpaper” in an exhibit in 1966: “There were drifting Mylar balloons, and this gorgeous and perfectly idiotic wallpaper. Everybody looked great, was stoned, and in my memory it was the absolute highlight of the nineteen-sixties—everything went to hell after that.” He also analyzes a selection of his favorite works from the show.
