The soundscape which I picked from the dreaded blue box was soundscape 7. A piece which filled me with a sci-fi mystery which I thought would compliment Close Encounters extremely well. Listening to it again today I found that it reminded me of the Super 8 trailer music and it prompted me more into the mindset of pursuing a mysterious and science-fictional road. After researching I have found that the soundscape I picked is from Star Trek III: The Search for Spock by James Horner and the reason why I thought of Super 8 when I re-listenined to the soundscape today is because the song Through the Window also by Horner is played through the soundtrack.
