"Il gatto a nove code" (The cat o `nine tails), filmed in 1971, is the second film by Dario Argento, a horror thriller still distant from his horror works for which he will later become famous on an international level. The collaboration with the composer and conductor Ennio Morricone, already known for his work on Sergio Leone's western movies, is here renewed after the success of "The Bird with the Crystal Plumage", and will continue with the third installment of the 'zoological trilogy', "Four Flies on Grey Velvet".A1 Ninna Nanna In Blu A2 1970 A3 Sottintesi A4 Parabola Del Paradosso A5 Parabola Prima A6 Parabola Seconda A7 Dissociazione B1 Dissociazione Seconda B2 Passeggiata Notturna (Movie Version) B3 Metafora Finale B4 Piaccaggio B5 Ninna Nanna In Blu (Movie Takes Variation)
