Kinda surprised there isn't a thread for this already. I own the scores to all five films in the series now, plus the second AvP score. Thought the mishmash of conductors might make for an interesting discussion. I'll try and come up with some thoughts. Alien Alien's score is spooky, resonant, and not very loud except for a few times. I've always found it's opening notes to be very spooky and quite iconic: Spooky Alot of the film is like this-it's very dissonant and almost asymetric-sounding. Incredibly fitting work by Jerry Goldsmith. Aliens, in sharp contrast to the original film, is very testosterone-loaded, and so is it's score. It also has what's become the standard for action movie trailer music, Bishop's Countdown, which is an absolutely incredible piece. I don't listen to it as much as I used to, but I still enjoy the heck out of it: Bombad Bishop Alien 3 and 4 I couldn't really find instantly-recognizeable pieces for, so here are their opening titles: Alien 3 Fox Fanfare and Agnus Dei I like how the Fox fanfare kinda goes into a scream at the end. Alien Resurrection Alien 4's opening is good. I guess. I laughed at the little bug. Anyway, Prometheus! I adore this score.* Of note: Life A Friend From The Past And Collision I have the 2nd AvP score as well, but can't remember much about it. Only saw the film once and have zero desire to watch that again. So..thoughts? Angry rants? Blank stares? *It rhymes.
