“Marjorie Strider: Girls, girls, girls,” at Galerie Gmurzynska on New York’s Upper East Side, is a blast. It is also, at least partially, a blast from the past. The solo retrospective, open until the end of this month, is a medley of work produced by the Pop Artist that spans from 1963 until her death in 2014. Strider rejected the minimalism pursued by the contemporary art cool kids. Instead, the Oklahoman went big, bright, and exuberant.
