It's an LP of 1959 field recordings of obscure Mississippi bluesmen. The performances are raw and electrifying. Even better, its a superb recording. On the right gear you can hear birds chattering in the trees way off to the side, seemingly from outside your room, on one track. On another you can hear the floorboards creaking under the musician. There's a duet between a fiddle player and guitar player that has such precise images that you can perceive them moving about slightly during the song. The last song on the second side is an astounding recording of a music therapy session in a mental hospital.
