“Crying the blues” perfectly describes the style of Sleepy John Estes. His music is not very complex, and he was a solid, but not a great guitarist.
Instead, Estes is known more for his ability to write about universal themes and to sing with deep emotion. He was a big influence on early bluesmen like Big Bill Broonzy and Arthur Crudup. He also was a big inspiration for later players like Michael Bloomfield, with whom he worked in the 1960s.
“Drop Down Mama” is a song of his that has re-surfaced several times. Sleepy John Estes and Hammie Nixon recorded it in 1935.
