Absolutely. And what is little remarked-upon is that the musical cross-fertilization worked in both directions.
Most of the Delta blues cats were tremendous country music fans, and listened to the Grand Ole Opry religiously, incorporating many of the songs they heard into their own repertoires. No less a titanic figure than Howlin’ Wolf stated that his trademark wolf howl was directly influenced by Jimmie Rodgers’ yodeling.
Vocal styles, instrumental licks, and songs flowed freely between the genres. It’s no accident that a song like “Sittin’ on Top of the World” was found in the repertoires of black bluesmen and white Western Swing bands alike.
Yeah, it’s a popularly-held “fact” that white people stole blues from black people and made a lot of money on rock n’ roll. That’s powerfully revisionist, though. It doesn’t reflect reality. I’m not saying that black musicians weren’t cruelly taken advantage of. They were. Charley Patton died a pauper, while his songs made record companies a lot of money (Jimbo Mathus will always have my respect for his album “Songs For Rosetta”. He donated all proceeds from the album to Charley’s widow, Rosetta.) But in places like Memphis and Muscle Shoals, where black blues musicians and white country musicians met and mingled and played together, magic happened.
The public radio station in Kansas City has a four-hour blues program every Friday and Saturday night. Here is a link to their audio archives. It’s a pretty good mix of many different styles of blues, along with some soul, R&B, and zydeco. Give it a listen, you’re bound to hear something you like.
