Off the "Song From The Hill" 2lp by the Wind Harp - a giant (9,1 meter) Aeolian harp designed and built by (then) 22 year old Thomas Ward McCain on a hilltop in Chelsea, Vermont (USA) - as recorded by Chuck Hancock and Harry Bee for United Artists in 1972. (Vermont is not California, bloggers!) The 2lp's opening track "Beginnings" was used on the soundtrack to William Friedkin's "The exorcist" (1973).
