This work of ultimate peace was recorded by David Storrs and Robert Slap in 1983 for Malibu-based Valley of the Sun publishing label. The tape is no longer available for purchase anywhere.
Storrs has been quoted as saying that "the album was experiment inspired by - and incorporating - a set of sounds from the plasma wave experiment which was riding aboard NASA's Voyager I and Voyager II space probes, the recording of which had recently been released to the public."
I first found out about this recording through Greg Davis's Crystal Vibrations blog and have listened to it probably around 100 times. Perfect for inner travels to outer regions.
