This is taken from an album of spaghetti western themes that came out on United Artists records in the late 1960s. It has a similar sound to other releases of the era on that label, probably because Leroy Holmes was a staff arranger. I can definitely hear Al Caiola's guitar playing.

To my ears, the arrangement also has a hint of Quincy Jones's work on 'The Italian Job'. It's an upbeat, jerky track with a bassline so percussive that it almost sounds like part of the beat. The melody is carried by guitar, horns, and also some nice wordless vocals (right near the end there's an incredible descending vocal swell that's really something).

Overall, this has a slightly menacing, very hip sound. It might even work on the dancefloor!
