James Cotton has a style I've always liked. He does this three note turn around thing in a lot of his tunes like Cotton Blues for example. He started out learning his style from Sonny Boy Williamson and later played with Muddy Waters (12 years).
I would like to mention Pat Hayes also. He plays with Lamont Cranston Blues Band. A Mpls.MN based band. Pat plays with a fever when he has the harp in his hands. He does this number called E-jam that makes my entire body ache with a joy. Pat is so smooth and expressive on the harmonica, it is always a delight to hear him.
I have many more favorites I could mention. Charlie Musselwhite, Sugar Blue, Gary Primich, to many to mention!
