well....i guess i can give you this idea cause i prolly wont get to it, or have the patience to do it.
this is THE idea you're looking for. the only problem i can think of is cutting the song down to a time that someone won't be an old man when they finish it.
Artist: Astral Projection
Song: Enlightened Evolution (Remix)
i know it has something that sounds like there's submarine pings in it (yknow those underwater "ping" sounds that movies have?). Plenty of dramatic and weird sounds for you to play with as well. You may wanna look at the original, but i think the remix is better.
