She was a crucial part of a cultural movement in the 1980s. Now a first solo exhibition in 15 years will allow her work to shine

From the 1980s to the early 2000s, artist and archivist Rita Keegan fervently collected and preserved newsletters, leaflets, photographs and exhibition literature from the British black arts scene. “It [didn’t] matter how fabulous the show – if you didn’t have the ephemera, it was hard to say that you existed,” she told the Art Newspaper last summer. “It’s very easy to be written out of history, if you don’t have those pieces of paper.”

Boxes and files stored behind the sofa in Keegan’s living room and a garden “shedio” in her south London home are a portal to the past, specifically, into the seminal British black arts movement founded in 1982. This pivotal moment in art history saw artists such as Sonia Boyce, Eddie Chambers, Denzil Forrester, Lubaina Himid and Maud Sulter galvanised to create and curate works together in the aftermath of the 1981 Brixton uprisings and in response to their marginalisation from the mainstream art world.
