Makes sure to explore different styles of Blues and acoustic vs electric. There is a lot of variety. Here are some artists to pursue (certainly NOT an exhaustive list). I've listed one or two album titles, too, as good starting points:
Butler, Wild Child - Wild Child Butler
Dixon, Willie - The Blues Every Which Way (with Memphis Slim)
Guy, Buddy - Going Back to Acoustic
Hammond, John - So many roads
Hatch, Little
Hooker, John Lee - Boogie Chillin' | Get back home in the U.S.A. | Sings the Blues (ThatÂ’s my story)
Hopkins, Lightnin' - Goin' Away | Lightnin'
House, Son - Father of the Delta Blues
Hurt, Mississippi John - The Best of Mississippi John Hurt
Johnson, Robert - King of the Delta Blues Singers, Vol. I
Lenoir, JB - Alabama Blues
Slim, Memphis -
Waters, Muddy - Folk Singer | Sings Big Bill Broonzy
Wells, Junior - Hoodoo Man Blues
Williamson, Sonny Boy - Keep It To Ourselves | The Real Folk Blues
Enjoy your explorations!
