Artist Michael Craig-Martin, the man who helped foster the development of the 'Young British Artists', discusses the early work of one of his most famous pupils, Damien Hirst.

Artist Michael Craig-Martin was an influential teacher at Goldsmith's College, London in the 1980s, where he became mentor to a gifted group of students, later known as the 'Young British Artists'. Among them was Damien Hirst.

TateShots caught up with Craig-Martin at Tate Modern, and asked him to revisit that fertile period, which saw Hirst create his first Spot paintings, Medicine Cabinets and his iconic installation 'A Thousand Years'.
