Yes, but both TBWP
and PA are post modern horror films, and the subgenre they belong to negating the need for "soundtracks" at all, almost like a scary version of Dogme 95 IMO.
music is a large part of creating an atmosphere within cinema...il refer to B Hermann's Hitchcock scores here as an easy example...get it wrong and you scupper the film.....(
phenomena) but getting it right usually makes a film a more rounded experience....il use The Exorcist here as the ST reflects the polarising ambience within the film...light/dark, quiet/noisy etc which symbolises the turmoil that the characters and by proxy the audience feels....
well, thats the bits i like anyhow....
