need some suggestions for Acoustics Blues

Wild child butler is pretty good. Availble via acousticsounds.com

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!

Son House needs to be on the list.
I also second the Mississippi Fred McDowell suggestions.

And Mississippi John Hurt, folk/country type delta blues.
Also, Sonny Terry and Brownie McGee, they have done a few albums together.

How about breaking the gender barrier with Rory Block.
