Video art dominates the international art world to such an extent that its heady days on the radical fringes are sometimes overlooked - often unknown. 'Video Art, A Guided Tour' is an essential and highly entertaining guide to video art and its history. Elwes, herself a pioneer of early video, traces the story from the weighty Portapak equipment of the '60s and '70s to today's digital technology, from early experiments in 'real time' to the 'new narrative' movement of the '80s. She also examines video's love-hate relationship with television. Artists discussed include amongst many others, Nam June Paik, Nan Hoover, The Duvet Brothers, Dara Birnbaum, Bill Viola, Pipilloti Rist, David Hall, Gillian Wearing, Stuart Marshall, Stan Douglas, Smith & Stewart, Steve McQueen and Sam Taylor-Wood.
