Gary D. Davis, known as Reverend Gary Davis and Blind Gary Davis, was a blues and gospel singer who was also proficient on the banjo, guitar and harmonica. Born in Laurens, South Carolina and blind since infancy, Davis first performed professionally in the Piedmont blues scene of Durham, North Carolina in the 1930s, then converted to Christianity and became a minister. After moving to New York in the 1940s, Davis experienced a career rebirth as part of the American folk music revival that peaked during the 1960s. Davis' most notable recordings include "Samson and Delilah" and "Death Don't Have No Mercy".

Piedmont blues refers primarily to a guitar style, which is characterized by a fingerpicking approach in which a regular, alternating thumb bass string rhythmic pattern supports a syncopated melody using the treble strings generally picked with the fore-finger, occasionally others. The result is comparable in sound to ragtime or stride piano styles. Blues researcher Peter B. Lowry coined the term, giving co-credit to fellow folklorist Bruce Bastin. The Piedmont style is differentiated from other styles, particularly the Mississippi Delta blues, by its ragtime-based rhythms.
