It actually sounds kind of like a swarm of locust and creepy at the same time. Almost as if there were backmasking going on at the same time. Also the locust sound kind of takes away from the main beat sadly so I can't truly give you the best of reviews on this either.
I hear some slight backmasking, locust which sound like static and some drums. This has to be one of the weirdest pieces I have seen so far. The only truly good part where I could get the idea of how the song was going was at the end where the locust/static sound got cut off before the end.
Well what the "locust" sound is, is actually me playing two harmonized tracks of sanshin. I got it to sound like that my putting a fuck load of Gverb on it and reversing it. Now it sounds like some bowed instruments.
About the beat and the sanshin: Since this is an experimental/noise piece, I really started out with the sanshin because, originally, it was going to be the main riff for an oriental song called Lotus Fuck that I never finished (lol), so the "drums" were adlibbed into it and put on repeat. When you say that the parts are clashing you probably mean that they are off beat from each other, this was done on purpose because I like doing things off beat and off tempo as an artistic expression (in fact, I don't think any of the songs on that album go to a specified beat besides what I thought sounded nice and frequency measures).
I don't remember what backmasking is right now but I'll get back to that some other time. EDIT: Oh yeah duh, I remember know. Yeah there's backmasking on the sanshin parts and saz part.
The "drums": The percussion part of this song is a really cool in that I didn't use a percussion instrument. I took my baglama saz, tuned the whole thing to D and rapped on and struck it with my fingers and bottom half of my palm, that way when the instrument is struck, the strings resonate sympathetically and give it a unique character. I also used a lot of Gverb on this to give it that really different timbre. You only hear it for a little while toward the end but, in the original version, my D tuned saz is played, solo until the end of the song.
Influences: Well, it's a good thing that it sounds like Silent Hill since it's going in a Silent Hill fan game! When I made the song I was thinking of Silent Hill (which is one of my general influences), Turok 2 (with the Mantids and their Hive level being a factor in imagery) and Gears of War.
