A good Barbara Steele horror movie! I had once asked the same question over at another soundtrack forum... nobody really new the answer. I remember being suggested of CAM's release LA VERGINE DI NORIMBERGA by Ortolani also directed by Antonio Margheriti which also includes George Riviere in the cast of actors just as in Castle Of Blood but it's not the same movie. I have searched and searched on numerous occasions with no results. Ortolani's score music most likely has never been released. Probably not even available for a release. Digitmovies might be of help though. I had asked them once about another possible Italian score release and they responded almost immediately. They were going to request it to their department to try and see if they could get it released.
