‘Picasso Black and White,’ at Guggenheim
Picasso had an ability to combine his genius with a level of sustained and self-renewing intelligence that was frankly astonishing. You can see that intelligence on display in one of the great Picasso shows of recent decades (and oh boy, haven’t there been a few). “Picasso Black and White,” at the Guggenheim Museum in New York, surveys the Spaniard’s entire career. But it focuses on the work he made in shades of black, white, and gray.
