Terry Setch can lay claim to being the most underrated artist in Britain. Not that the Cardiff-based Londoner has been entirely neglected: acclaimed as one of Britain’s most powerful painters by his contemporary John Hoyland, he’s been garlanded with awards, granted a retrospective at The Serpentine and was recently made an RA. Yet Setch (born 1936) has still had nothing like the recognition he deserves as one of Britain’s most intelligent and inventive painters. And the crime for which he’s been sentenced to this relative obscurity: simply, not being based in London, but in Wales.
