The exhibition Tracce di un seminario, curated by Giacinto di Pietrantonio and Angela Vettese, documented the various phases of the workshop held in Como by Allan Kaprow, a central figure of post-war American art and experimenter since the fifties of the most revolutionary art forms such as Environment and Happening. The thirty-two young artists selected to take part in the workshop - coming from about fifteen different countries, from Canada to Bulgaria, from Indonesia to Finland - were involved in a series of theoretical, practical, and even playfully physical activities, which intended to create awareness about common gestures that are normally performed automatically.

Tracce di un seminario was a survey of the work of the thirty-two participating artists through the materials they chose to present: projects of works, photos, drawings, videos, and models. It returned the richness and multiplicity of the different personalities, researches, and experiences that crossed each other for a short time under the leadership of Allan Kaprow.
