It takes just the mention of Conceptual Art to make most people glaze over. This is a shame if not ironic, as the movement—that specifically refers to a group of artists of the 1960s and ‘70s but has become a term applied to almost anything since—aimed to smash the elitism and navel gazing of the art world, defy its preoccupation with paint and aesthetics, and challenge its view of society as a ‘contaminating influence’. This show centres on a group of such rebels—socially savvy Americans and Brits such as Terry Atkinson, David Bainbridge, Charles Harrison and Joseph Kosuth—all of whom advocated equality, viewer engagement and topicality above all, starting the journal Art - Language in 1969 to that effect. This cheap-looking publication was quite an affront, for what, indeed, was the art? Was it the words? Something they described...? Such fundamental questions abound in this exhibition that shows works from the Philippe Méaille Collection. And, as with all MACBA shows, it’s best to avoid the confusing leaflets and think ‘beyond the images’.
