I really liked this one. The "ocean splashes" really add some nice depth. It reminds me of that first scene in Inception where the old guy is standing on a beach. Dark, brooding, thoughtful, mysterious. And of course there were wave noises. ;-)
There are some really subtle noises buried under the big sweeping synths that add a lot to the sound too.
If you've never heard of the band Biosphere you should check them out, particularly the album Substrata and definitely the song Poa Alpina, which, while it doesn't sound the same, gives me the exact same mysterious and creepy feel as your song.
This is a really high compliment btw, I love that song.
I think this shows some of the flaws of NG's rating system. I usually reserve 10/10 for pieces that really knock me out of my seat. This one didn't do that, but the atmosphere is perfect. If you coupled it with a few more songs of equal quality and made it into an EP or something, it could be stellar, and even better than your conventional explosive 10/10 song.
Maybe I just need to rethink my rating system... meh oh well.
