Kurt Andersen and MIT Media Lab Scientist and composer Tod Machover untangle the crossed wires of art and digital technology, with stories about legendary dancer Merce Cunningham’s embrace of computers to choreograph his new work, a musical art form constructed entirely from electronic glitches, and writers, film editors, and designers who love — and hate — how computers have changed their crafts. And director Bruce Beresford and composer Stephen Endelman talk about Bride of the Wind, their new movie about Gustav and Alma Mahler, and design critic Veronique Vienne examines a uniquely American piece of furniture — the coffee table.
