There are many kinds of blues, but as far as I am concerned the center of the blues lies in Mississippi! Blues from the Delta is pure and raw, and the special sub-genre that gets me going is Hill Country Blues. Mississippi Fred McDowell is a founding father, while RL Burnside and Junior Kimbrough were the heroes of the revival of the 1990s and 2000s. Today, Hill Country Blues is very much alive with modern artists such as North Mississippi Allstars, Ligthnin Malcolm, Cedric Burnside (RL's grandson) and Kenny Brown.
The rhythmic style of the Hill Country is well illustrated in this early coverage of Fred McDowell (who does not play no rock'n roll):

This is Junior Kimbrough, playing in his own juke joint:
