Apparently it’s an original composition, but I couldn’t help but think of Personal Jesus by Depeche Mode.  I’m not the only one, someone else mentioned it in the comments on the video (on the Vimeo page, which unfortunately isn’t embed-able so you get youtube above) and Diego replies:

A friend of mine, fan of DM, told me the same.
I know some of their music, but I wasn’t thinking about that song. I was inspired by the hours of western music I’ve heard in films, it’s that kind of triplets “horse galloping” pattern you hear in the “bunch of bad-ass cowboys going to place x to fix the situation” kinda scene : )

Which I makes me sort of wish I knew how to do 3-d computer animations and such to be able to make the scene that goes with that.

For some reason it also makes me think a bit of the general vibe of Cowboy Bebop, though that admittedly usually has more horns – perhaps the general Western vibe.

Also, things like this are why I oscillate wildly between thinking I’d really like a really little place in the city with minimal stuff, and (where this comes in) a few acres of land next to a junk yard somewhere out in the country where I could hack together things like this without bothering people in the next apartment (a large reason why I don’t play my tuba more).
