Hey Azizi,

Welcome to a new world. It get's real good.
I personally love the acoustic, traditional side of the blues. It's what got me really deep into acoustic music alongside people like Woody Guthrie, Bill Monroe and the Carters. I would suggest some of my favorites:

Robert Johnson
Son House
Skip James
Willie Mctell
Blind Boy Fuller
Mississippi John Hurt
Leadbelly
Tommy Johnson
Rev. Wilkins
Lemon Jefferson
Fred McDowell
Henry Thomas

Howlin Wolf
Sonny boy WIlliamson
Muddy
Buddy Guy
Taj Mahal
