Great posters, and the horror film music he chose was gorgeous.
The first theme was from "Blood on Satan's Claw," and the second from "Theatre of Blood."
Growing up I used to love the classical-inspired music of these older horror flicks.
Today's horror film "scores" mostly give me a headache, because it's mostly non-melodic dissonance meant to make the viewer as uncomfortable as listening to nails on a chalkboard. How clever.
There are certainly those kinds of elements used in certain types of horror film scores today (or to emphasize certain scenes, moments, to make one jump or create a hyper moment), but this kind of composition isnt what comprises the vast majority of any horror film score. Not by a long shot. (Unless that's what the director specifically wants, from start to finish, which is always his/her prerogative).
One movie that comes to mind where much of this dissonance was later used (and after the film's original score was thrown out) was in
The Exorcist. Yes, Mike Oldfield's
"Tubular Bells" was the movie's theme track, but the rest of the movie is filled with sounds, screeching violin pieces, etc. And, imho, it worked very well.
