Not simply a case of nepotism. F.F. Coppola's choice to use his brother-in-law (Talia's husband) to soundtrack his creepfest was spot on. At times, this reminds me of some dark Nurse With Wound type shit. Definitely not like the hard boiled funk he conjured up for the Taking of Pelham 123 soundtrack (the original, natch) the same year. Lots of haunting piano, weird creaks & crashes, borrowed dialog. Perfect for Coppola's & Hackman's finest moment. Such a great soundtrack for such a great film. Worth it.
