ALIEN score

i am very fond of Jerry Goldsmiths score. Although all of it is fantastic, i particularly enjoy the kind of strange parts that were subdued in or cut from the film which make use of the instrumentation like the conch, serpent, digeridu, and other horn like instruments - typically meant to represent the appearance of the alien- such as the following tracks from various versions of the score: Hanging On Parker's Death The Face Hugger does anyone happen to know of any other examples of music where i might find this kind of sound/instrumentation and style ?
