David “Honeyboy” Edwards, the once-itinerant Delta blues singer and guitarist who late in life won two Grammy Awards, toured almost until his death Aug. 29 at age 96.

Such was his longevity that, as a young man in Mississippi, he performed with Robert Johnson, one of the most influential and enigmatic bluesmen of all time. Late in life, Edwards improvised in a Connecticut nightclub with Rolling Stones guitarist Keith Richards.

Edwards’ death, from congestive heart failure at his home in Chicago, was confirmed by his manager and harmonica player, Michael Frank.

Edwards won a 2007 Grammy for traditional blues album with the recording “Last of the Great Mississippi Delta Bluesmen — Live in Dallas,” a collaboration by Edwards and three other elder statesmen of Mississippi blues: Pinetop Perkins, Robert Lockwood Jr. and Henry James Townsend.

Last year, Edwards was awarded a lifetime achievement Grammy.

His spirited performances resounded with his life experiences. He had been a sharecropper, hobo and juke joint entertainer.
