I am not sure that the player that "mopped up" our friend here was a bona fide Robert Johnson impersonator--there are a lot of people who play RJ tunes, but damn few who play them the way RJ did--For one thing, he, and his contemporaries, played a lot louder than folks today. Forget those "lite" strings-- they played on busy streetcorners and in noisy jukes, where they had to draw attention to themselves without amplification--

At any rate, Henry Thomas' style actually was a precursor to the RJ style, a bit more simple, a bit more raw-- make it nice and loud, and you'll blow everyone else away.
