[Harp-L] Earliest Chromatic Blues songs?

[michael rubin <michaelrubinharmonica@xxxxxxxxx>]

Alright, we all know Walter's Crazy Mixed Up World and Blue and Lonesome, etc.
Who was playing chromatic blues before Walter?

Although I will accept answers like Minevitch and Harmonicats' etc.  I
am talking about blues players who seldom if ever would record outside
of the blues idiom.  (Not that they could not play whatever style of
music they wanted to)
