Rivers and Tides features the work of artist and sculptor Andy Goldsworthy who specializes in ephemeral sculptures made from elements of nature. This 2001 Scottish-German documentary follows Goldsworthy as he pursues his favorite medium: water. The artist sculpts ice from trees and loose rock in forests and on shorelines. The sculptures become overgrown with plants or disappear with the day's tide, yet maintain their spiritual character as they become nature once again. Filmmaker Thomas Reidelsheimer captures Goldsworthy's work in stunning cinematography, bringing to the surface the artist's concepts of the relationships between light, color, movement, balance and fluidity in the natural world. The film features some of Goldworthy's most notable creations including stone walls that weave through hundreds of feet of forests and streams, sculptures made entirely of icicles and other masterpieces. Through his use of natural materials and intricate sculptures, Goldsworthy showcases the fragile relationship between man, art and nature.
