It sounds like something Walter Geertsen or Phillip Collignon played to me over the phone in the 1990s , I don't remember which guy. Both were record dealers and collectors. It was a heavy UK private from 1972 or 1973 and they wanted a lot of money.like $4000 dollar. It was probably Walter, because he had ultra rare LPs at that time.
I think the band or LP was called LUCIFERS DAUGHTER or something similar and it did not have a cover which decided me not to buying it. Never heard about again. The clip has memorable voice and Organ that I remember. Different track . Lyrics I remember were about a journey into Hell.
