Avedon Warhol, Gagosian Gallery

One was the wiry fashion photographer whose stark, realist portraits defined the medium for half a century. The other was the bleached and tipsy pop-Artist who started an artistic revolution from his tinfoil lined Factory. Both were post-war American artists who glamourised and ultimately changed art for good, by bringing the outside in.

This February, Richard Avedon and Andy Warhol's art will be presented in Gagosian London, for the first major art exhibition that sees a selection of the artists' work, from the '50s to the '90s, displayed side by side.

The America in which Avedon and Warhol lived and worked was fast evolving, both politically and socially. Prosperity and materialism met slackening of rigid morals, to make a fast-paced hard-living society. Both artists dealt with with mainstream culture, but also subcultures, underbellies, outsiders, radicals and celebrities.

The tyranny of political power is another shared concern, and the exhibition will contain works such as Warhol's enormous silkscreen portrait of chairman Mao, and Avedon's 1976 The Family - a project that attempted to crystallise the post-Watergate political atmosphere by making portraits of the political elite at that time.

We're particularly excited to see Avedon's sexually charged group portrait Andy Warhol and Members of the Factory. In 1969, Avedon summoned to his studio the motley crew of actors, models and hangers-on that gathered around Warhol.

Both artists worked with portraiture, so you can expect to see some familiar faces at this Gagosian show including Marella Agnelli, Bianca Jagger, Jacqueline Kennedy, Marilyn Monroe, and Rudolf Nureyev.
