>>149430338I'm with you in that it didn't feel out of place to me, but for a different reason. Musically, spaghetti westerns often occupy a similar space as surf rock and rockabilly. It's common for surf rockers to do covers of spaghetti western themes largely thanks to Ennio Morricone non-standard orchestrations and Allessandro Allessandroni's twangy jaguar guitar.
"For a Few Guitars More" is a compilation of surf covers of Spaghetti Western Themes.

In both the surf and rockabilly scene, the classic greaser look is still very much en vogue. I know it might seem like a stretch, but the fact that Tara and Zach hired Dom Kreep to do the music for the pilot (which ended up being incredibly surfy), seems to indicate that they're clued into this connection. As someone who gets nerdy about this kind of music, I didn't find Snag's look to be anachronistic or out of place. I just thought he was cool.
