Richard Dorment is enchanted by a new show of video art. In the 60s, he writes, video art opened up new possibilities for artists. “Art lightened up. Short video pieces could be funny, impromptu, sexy or apparently inconsequential – and yet be serious works of art. And whether artists worked behind the closed door of their studios or in a public gallery, the range of subject matter they could explore expanded dramatically. Nudity, eroticism, humour, physical endurance, and relationships between people – video enabled artists to treat all these themes with a new immediacy, informality and spontaneity.”
