Children of the Stones was a complex and disturbing television drama produced for children by HTV in 1976. I remember being literally petrified by this programme, particularly the title sequence. As a youngster, I found its soundtrack both intensely otherworldly and deeply troubling. The music was composed by Sidney Sager who used a combination of a cappella vocalizations of a single, repeated Icelandic word ("Hadave") to create a terrifying and dissonant score. The vocals were provided by the Ambrosian Singers who during their long career have provided choral work for both Ennio Morricone and Nino Rota. The series was filmed at Avebury, Wiltshire during Summer 1976, with interior scenes filmed at HTV's Bristol studio. The score for this series has never been commercially issued, which is a shame as both the "
Start Title" and the " Ritual And End Title" are some of the scariest music I've heard on television.
