Country has officially become the shittiest genre of music there is.

Parker.. klezmer? I could just google it, but do you mind giving me your spin?

Klezmer features a lot of harmonic minor tonality, which that song features. That tonality is featured in a lot of Mediterranean music, as well -- but klezmer adds in elements of Gypsy/Roma music which the Ashkenazi brought into the mix from their experiences in Eastern Europe. It's rhythmically more sophisticated than, say, American folk music, probably from its cross-pollination with jazz in the 20th century.

I'm only familiar with the New York expression of klezmer that has come about in the last thirty or forty years, so I'm a neophyte myself. But I can certainly hear its influence in that song, harmonically.
