Critical acclaim for a group of recent art school graduates has put Scottish art, and Glasgow in particular, firmly on the international map. Two people at the forefront of this unexpected renaissance are Stephen Campbell and Adrian Wiszniewski. Within three years of leaving college, their pictures already hang in the Tate Gallery, the Museum of Modern Art and the Metropolitan Museum in New York, and are sought after by museums and collectors in Europe and North America. In this week's Arena, the former classmates meet again to take stock of their meteoric rise and to compare notes on the art scene in Britain and New York.
