Potential Albums Picks:
I put my dream picks on top with links, but I think I've got all the other suggestions from others.
April (1969 Blues Album):
Mississippi Fred McDowell - I Do Not Play No Rock N' Roll
Freddie King - Freddie King is a Blues Master
Big Mama Thornton - Stronger Than Dirt
Taj Mahal - Giant Step / De Old Folks at Home
Howlin' Wolf - The Howlin' Wolf Album
Earl Hooker - 2 Bugs and a Roach
---- More Classic Rock than Blues, but.. -----
Johnny Winter - Johnny Winter (or Second Winter)
Janis Joplin - I Got Dem Kozmic Blues Again Mama!
Fleetwood Mac - Then Play On
Blind Faith - Blind Faith
Led Zeppelin - Led Zeppelin II
Led Zeppelin - Led Zeppelin I
May (1971 Instrumental Soul):
King Curtis - Live at the Fillmore West
Booker T & The MGs - Melting Pot (Highly unlikely due to it's recent reissue)
James Brown - Sho is Funky Down Here (Just had a RSD reissue though through Now-Again, so I doubt it)
June (1970 Soul-Jazz):
Eddie Harris - Live at Newport
Jimmy Smith - I'm Goin' Git Myself Together
Jimmy McGriff - Something to Listen To
Herbie Mann - Push Push (Possible the worst album cover of all time.)
Grant Green - Carryin' On
Melvin Sparks - Sparks
Freddie Hubbard - First Light (I have this and it's great, but not what I think of when I think of Soul-Jazz. Also a recent ORG reissue).
Charles Kynard - Afro-Disiac (I doubt this as it got a recent Jazz Dispensary reissue.)
