ART21 is an award-winning series of 24 programmes in which 100 contemporary artists talk about their creations, the way they work and their individual view of art. How do artists evoke and transform time in their work? Can a work of contemporary art be timeless? How does contemporary art relate to art of the ancient past, to nature and to the rhythms of the life? The “Art in the Twenty-First Century” documentary “Time” explores these questions through the work of Charles Atlas, Martin Puryear, Paul Pfeiffer, Vija Celmins and Tim Hawkinson, including an introduction by Merce Cunningham.
