James Turrell, artist. James Turrell began working in the 1960s, when many artists abandoned conventional painting and sculpture for new media and an expanded definition of art practice. In this podcast recorded on April 7, 2002, at the National Gallery of Art, Turrell discusses the four decades of his career spent creating installations based on the pure experience of artificial and natural light. His work, which ranges in scale from single rooms to the vast, complex Roden crater project in Arizona, has established him as one of the most original visionary artists of our time.
