Mike Kelley at the Tate Modern review – an uncomfortable pop culture show feels a bit like being skinned alive

Growing up in postwar working-class Detroit, Kelley was always an outsider. One of the first artists to explore multiple media, from performance to video, sculpture to drawing, sewing and fabric toys, inspired by the feminist art movements of the 1970s. He was an artist of his own time, but in many ways also an artist of our time, challenging gender stereotypes, exploring craftsmanship, and confusing the masculine austerity of the gallery environment with the dirty, the soft, the childish, the childlike and – horror – that Popular.
