Hi,
I didn't find topic of instrumental (acoustic) counry blues, so here is it. My humble quess is that most of them are guitar solos but I remember heard harmonica and madolin tunes also.
It would be nice to have list of them. My memory doesn't serve me very well, but here are few for the start.
Sylvester Weaver: Guitar rag
Mississippi John Hurt: Spanish Fandang (I'm not sure if there are two different songs that has same name), Shake that thing (humming part of the tune)
Elisabeth Cotten: Spanish Fandang, Run run run, Washington blues, Holy Ghost, unchain my name, Vestapol, Honey babe your papa cares for you, Wilson rag, Graduation march, Gaslight blues, Jenny, Street blues, Casey Jones, Boddie's song, Take me back to Baltimore, Fox chase, Ontario blues, Home sweet home
Blind Willie Johnson: Dark Was the Night, Cold was the Ground (almost instrumental though Wilie hums and it's kind of singing or other instrument)
Sam McGee: Franklin blues
Etta Baker: Piedmont blues
Blind Blake: West coast blues, Guitar chimes, Southern rag, Blind Arthur's Breakdown
