Where are the Simian Distress Screams taken from?
The following is from Brandon Jamison concerning the Simian Distress Screams found at the beginning of "What God Wants, Part I":
You'll notice that these sounds are borne from the sound of muffled explosion sound, a bang. I think these sounds are taken from the movie "Greystoke: Legend of Tarzan." In the first 10-15 minutes of the movie, a shipwrecked husband, wife, and infant have set up crude living quarters on an island. The apes get into their home and discover a gun. In examining the piece, they inadvertently shoot it, and react with these violent sounds. I think that is where this this sound is from.
