As blues is a wider category than non-blues fans appreciate, here are some categories and artists to check out:
Guitarists
Country Blues and Ragtime Guitarists:
Robert Johnson, Mississipi John Hurt, Blind Boy Fuller, Blind Blake, Blind Willie McTell, Blind Lemon Jefferson (a pattern is emerging here) Alas, these are all dead as well as blind (Well allright, Robert Johnson and Mississippi John Hurt weren't blind but there's no doubting their deadness even though their music lives on.
This is a great 3-DVD set featuring Rod Piazza, Billy Branch, James Harman, and Studebaker John on harps.
Singer guitarist George Baze also impresses but the sad news is that he is no longer with us.
