I wondered what piece or pieces in the Country Blues canon strike you as being the least susceptible to being accurately reproduced. I have some choices of my own along those lines--mostly stuff where the right hand is mysterious/imponderable. I'd be interested in any tunes you or other visitors to the site would consider to fall into this category. A few nominees from me:
* "Jesus Make Up My Dying Bed"--Blind Willie Johnson;
* "Paddlin' Madeline Home"--Kokomo Arnold;
* "Down the Dirt Road Blues"--Charley Patton
Any others out there?
