Bump,γιατί αλίευσα από την wikipedia (ναι,από την wikipedia :P) αυτό:
The musical forms and styles that are now considered the "blues" as well as modern "country music" arose in the same regions during the 19th century in the southern United States. Recorded blues and country can be found from as far back as the 1920s, when the popular record industry developed and created marketing categories called "race music" and "hillbilly music" to sell music by blacks for blacks and by whites for whites, respectively. At the time, there was no clear musical division between "blues" and "country," except for the ethnicity of the performer, and even that was sometimes documented incorrectly by record companies.
Μήπως λοιπόν,το country με το blues έχουν αντίστοιχη σχέση με την μουσταλευριά και το... μούστο?
Επίσης το αποπάνω ποστ είναι πολύ ενδιαφέρον!
