Well, the regions were where the genres were really exemplified. I just gave you some of the true masters or pioneers of these regional genres. :)
If it's piano you're into check out Otis Spann, Memphis slim or Professor Longhair
For the harp: Little Walter, Sonny Terry, James Cotton
Robert Johnson, Howling Wolf, Muddy Waters. That's a good start. The real bluse material, all black men who know what blues is. Or knew.
Hey, there are no such things in blues, really. Baby please don't go is one of the most covered. From the real blues throught to heavy metal. I like pretty much all versions.
My suggestion would be to buy an early Robert Johnson album, all on CD/DVD now. And just listen. Hear the whole album. If you've ever heard that song "The Devil went down to Georgia", it's based on a fable that Robert Johnson was at a crossroads, a real one when the Devil turned up and offered to teach him guitar. He said yes. That's the fable.
Truly, it's not realy that kind of music that you have favouirite songs. Some, yeah but it's really the feel of the music and the emotion that is the blues.
John Lee Hooker, Nick Drake, Lightnin Hopkins, Son House, Nina Simone, Jimmy Reed, Kenny Wayne Shepard, Janis Joplin ( You love her or hate her), Stevie Ray Vaughn, Jimmy Hendrix, Peter Green, T-bone Walker, Blind Willie Johnson, Etta James, Ray Charles, Bonnie Rait, Solomon Burke, and Tina Turner.
