Here's another music sample for the trailer we're working on. This one is definitely getting closer to the right mood and feel. I played Mark a piece of music by The Necks from an album called Mindset - that I had been playing every morning, first thing over a week.
There were lots of sounds and undercurrents in it and this inspired the high tones towards the end of this version. It's funny how you ask for sounds to sound like something you already know and you end up with sounds that sound unique and therefore better than what you had originally heard.
