Jerry Goldsmith: The Droid
Ridley Scott's Alien is one of my favorite films of all times. While often labelled a science fiction film, it's really just a classic haunted house horror slasher in disguise.
Jerry Goldsmith's ingenious score plays a huge part in giving the film its harrowing quality, and when trying to think of ways to describe it all I could muster were random words such as oppressive, claustrophobic, chaotic, unpredictable, discordant, terrifying and sneaky.
Listen to the soundtrack really loud in headphones all alone in dark and you can almost feel the physical presence of alien itself in the room.
