Enter The Void looks great I am still at a loss as to why I have not yet seen it.
Night of the Living Dead soundtrack is perfect and I also like to put that film on with just the audio playing. Really like the use of "emergency broadcasts" thru out the film.
Eraserhead soundtrack is pure industrial soundscapes and It is also its own perfect atmosphere, cold and dismal by itself.
Dawn of The Dead soundtrack is flawless despite having some like children's music box muzac parts, the tension slowly builds in that music and it never gets old.
Goblin and Dario Argento's work together creating the very specific scores for his films may be one of the most overlooked aspects of why his work has earned so much critical acclaim.
Hermann Kopp's synth work on the NEKROMANTIK & DER TODESKING soundtracks is fucking excellent and I love it. I know many people here are probably fan's of those films, but I am adamant about them, I love nekromantik for its look, feel and most importantly its sound. Malsonous' sub label Aesthetic records has a vinyl LP gate fold of Kopp's music for these films, can't recommend this enough:

The Texas Chainsaw Massacre
Apocalypse Now REDUX soundtrack is an exercise in "the days when electronic music was laboriously performed with Moog, Arp and similar computers."

THX-1138 soundtrack had two components, a musical score composed by Lalo Schifrin and an abstract electronics based score by Walter Murch, who also helped to conduct the original Apocalypse Now soundtrack. THX1138 soundtrack is one of my favorite listens ever, aseptic sound environment. Walter Murch's sound masterpiece is THE CONVERSATION
