An enlightening exhibit at Madrid’s Museo Reina Sofia weaves together the ruptures of postwar art to focus on the interplay between readymade and spectacle in 1957 through 1962. Duchamp’s shadow broods large over the whole, which is punctuated by the death of Jackson Pollack and the dawn of the public careers of artists like Tinguely, Oldenburg, Klein, Johns. Necessary and promethean.
