“Night Flight” is perhaps the scariest and most effectively ambient of the thirteen tracks offered by Ennio Morricone on the soundtrack to Exorcist II: The Heretic. It moves slowly, echoing beautifully thin strings and pads beneath an atmosphere that evolves into full-on soundscape, incorporating the various “post-exotica” elements with which many of the album’s other songs are befit: There comes the whip cracks and babbling, the moans, chanting, and simple skin-drum sequences. It builds over five long minutes into an orgiastic climax, finally including hints of the film’s coda, sounding much at its denouement like the filmic satanic cult of Rosemary’s Baby (1968), preparing to defile and ravage. This track is interrupted in its playlist sequence by “Interrupted Melody”, a tune elsewhere examined in this series, followed by the closing song, “Exorcism”, a 58-second queue in which George Crumb’s threnody “Night of the Electric Insects” is channeled for the last time on the soundtrack. There is a flute sequence, a woman’s aria, bells do chime. It concludes The Heretic and tells us something: This is not over.
