Query: Simple bliss and the beginning of System 7

This is one of those amazing landmarks of 1970s music that came back to haunt everyone about a decade-plus later. Hillage and Miquette Giraudy here weave a complex, drone-based tapestry of ambience for an installation/chill-space at a UK music festival in 1977, but later artists of the rave-oriented ambient scene (such as The Orb and The KLF) grabbed onto what Hillage and Giraudy did here for their seed-sources, with The Orb clearly in acknowledgement of their debt as Dr. Alex Patterson was a collaborator/remixer/producer with Hillage and Giraudy's System 7 project. But System 7 really begins here, according to Hillage, with these two side-long flowing works of pure guitar and electronic tranquility. If you own The Orb's "Adventures...", you own a snippet of this; may as well go ahead and grab the whole thing, if you can.
