Presenter Kim Howells introduces Terry Setch as an artist who came to Cardiff in the 1960's and for over forty years has been a 'kind of artistic beachcomber'. He has taken as both subject and medium the rubbish that washes up on the shoreline of the Bristol Channel and incorporated it into a series of works that highlight our disposable society. In an interview with Setch and with archive film clips of him collecting rubbish from the beach he talks about the themes of man in conflict with nature. The Torrey Canyon oil tanker disaster of 1968 off the Cornish coast led to Setch producing a series of large scale works on the theme of oil pollution. 'Once Upon a Time There Was Oil' was acquired by the Tate Britain gallery.
