i first saw this film in about 1978, at a tiny private cinema club in Oxford, alongside "La Vallee" which was in French. "Crystal Voyager" is the original surfer movie, and the "Echoes" sequence which accompanies the ride inside the tube of a wave truly gives the eerie feeling of silence amidst the power of the wave.
Now, with the DVD, you can enjoy the eerie and atmospheric sounds of the early Pink Floyd soundtrack - just turn down the lights, put on some incense sticks, slip the DVD into the player, and you will be drawn into the beauty of the images and music. The music alone makes this a must-have DVD, and it will introduce you to the other-worldly early Floyd (Listen also to "More" and "La Vallee"), and if you are a surfer, your soul will rejoice during the main surfing sequence itself.
The narrator of this film is one of the founding fathers of modern surfing culture, and the story of his boat, and his surfing, and the music (contemporary to the action) com[plements this perfectly.
