You might try getting an older recording of Symphonie Fantastique - Hector Berlioz. It would work very well with the film. Many motifs from it were used in The Shining.
Then the beginning of this aria has a very dark mysterious vibe to it. I think it sounds close to what kind of soundtrack they would have used then.

I have loads of music to draw from, just ask what vibe you want, and I will be more than willing to supply.
