The Grady McMurtry Project, a website dedicated to preserving the legacy of Grady L. McMurtry, also known as Hymenaeus Alpha 777, Caliph of O.T.O., has published a series of correspondences between Grady and Led Zeppelin guitarist Jimmy Page that were exchanged between 1975 and 1977.
These letters include discussions of the possible renovations at Boleskine House and its significance to passages in Liber AL, and its possible use as a Profess House.
