This is an area that I haven't fully explored.

I really like "Spoonful" and just about everything else by Howlin' Wolf.

I enjoy the Robert Johnson recordings, probably as much for the legend as for the music itself (which is great).

"Tupelo" is a cool track from John Lee Hooker.

"Death Letter" from Son House.

Professor Longhair does a great rendition of "Jambalaya"

Pretty much everything from Lighting Hopkins and T-Bone Walker.

Nicolas, your jazz friend musta been in blues heaven ... :-)

Yes, he loved this compilation, especially 2 tracks :
Papa Lightfoot frantic version of "When the saints go marching in" at the harmonica (and singing witha To Waits-like voice through the harmonica mike)
and Robert Wilkin's "Prodigal Son", a live version 9-minutes long, very haunting (the rolling stones cover was very faithfull to it)
I wish you could hearthese songs someway
