need some suggestions for Acoustics Blues


What are your favorite artists/recodings for acoustic Blues besides Muddy Waters MSFL "Folk Singer" and Buddy Guy "Alone and acoustics" (got them already)? Dont you just love the sound of acoustic guitar, harmonica, and vocal sound of the human soul/spirit? Any suggestion is appreciated...

Blind Willie Johnson: The Complete Blind Willie Johnson (Sony)
Mississippi Fred McDowell: First Recordings (Rounder)
Mississippi Fred McDowell: You Gotta Move (Arhoolie)
Alvin Youngblood Hart: Big Mama's Door (Sony)

Only the last is a top-notch recording, but musically they are all amazing. Enjoy!
