MJH's ragtime-tinged style was more similar to east coast bluesmen like Blind Boy Fuller, Willie McTell, William Moore, Libba Cotten and others than it was to his Mississippi contemporaries playing in Delta styles. You might find a sampler from Biograph or Blue Goose or Revenant dedicated to East Coast or Piedmont Blues. A good place to ask this question would be at the Weenie Campbell forum which has plenty of knowledgeable country blues freaks.
