This one sounds like an old western without the ultra-cheesy elements that usually go with old western soundtracks. These include the "vibraslap rattlesnake" sound and men grunting nonsense syllables. The background rhythms are a little more modern too. I figure the electric hollow body guitar and minor key are enough.
Not one of my favorites, but it was something off the beaten path. If I always do the same styles and genres, I feel like I'm getting stuck in a rut.
