Country blues (also folk blues, rural blues, backwoods blues, or downhome blues) is a general term that refers to all the acoustic, mainly guitar-driven forms of the blues. It often incorporated elements of rural gospel, ragtime, hillbilly, and dixieland jazz. After blues' birth in the southern United States, it quickly spread throughout the country (and elsewhere), giving birth to a host of regional styles. These include Memphis, Detroit, Chicago, Texas, Piedmont, Louisiana, West Coast, Atlanta, St. Louis, East Coast, Swamp, New Orleans, Delta, Hill country and Kansas City blues.

When African-American musical tastes began to change in the early 1960s, moving toward soul and rhythm and blues music, country blues found renewed popularity as "folk blues" and was sold to a primarily white, college-age audience. Traditional artists like Big Bill Broonzy and Sonny Boy Williamson II reinvented themselves as folk blues artists, while Piedmont bluesmen like Sonny Terry and Brownie McGhee found great success on the folk festival circuit.

John Smith Hurt, better known as Mississippi John Hurt (July 3, 1893 or March 8, 1892 — November 2, 1966) was an American country blues singer and guitarist.

Raised in Avalon, Mississippi, Hurt taught himself how to play the guitar around age nine. Singing in a loud whisper, to a melodious finger-picked accompaniment, he began to play local dances and parties while working as a sharecropper. He first recorded for Okeh Records in 1928, but these were commercial failures, and Hurt drifted out of the recording scene, where he continued his work as a farmer. After a man discovered a copy of one of his recordings, "Avalon Blues", which gave the location of his hometown, there became increased interest in his whereabouts. Tom Hoskins, a blues enthusiast, would be the first to locate Hurt in 1963. He convinced Hurt to relocate to Washington, D.C., where he was recorded by the Library of Congress in 1964. This rediscovery helped further the American folk music revival, which had led to the rediscovery of many other bluesmen of Hurt's era. Hurt entered the same university and coffeehouse concert circuit as his contemporaries, as well as other Delta blues musicians brought out of retirement. As well as playing concerts, he recorded several studio albums for Vanguard Records.

John Lee Hooker (August 22, 1917 – June 21, 2001) was a highly influential American blues singer-songwriter and guitarist.

Hooker began his life as the son of a sharecropper, William Hooker, and rose to prominence performing his own unique style of what was originally a unique brand of country blues. He developed a 'talking blues' style that was his trademark. Though similar to the early Delta blues, his music was metrically free. John Lee Hooker could be said to embody his own unique genre of the blues, often incorporating the boogie-woogie piano style and a driving rhythm into his blues guitar playing and singing. His best known songs include "Boogie Chillen'" (1948), "I'm in the Mood" (1951) and "Boom Boom" (1962), the first two reaching R&B #1 in the Billboard charts.

There is some debate as to the year of Hooker's birth in Coahoma County, Mississippi, the youngest of the eleven children of William Hooker (1871–1923), a sharecropper and Baptist preacher, and Minnie Ramsey (born 1875, date of death unknown); according to his official website, he was born on August 22, 1917.

John Renbourn (born 8 August 1944, Marylebone, London, England) is an English guitarist and songwriter. He is possibly best known for his collaboration with guitarist Bert Jansch as well as his work with the folk group Pentangle, although he maintained a solo career before, during and after that band's existence (1967–1973).

While most commonly labelled a folk musician, Renbourn's musical tastes and interests take in early music, classical music, blues and world music. His most influential album, Sir John Alot (1968), featured his take on songs from the Medieval era.

John Renbourn studied classical guitar at school and it was during this period that he was introduced to Early Music. In the 1950s, along with many others, he was greatly influenced by the musical craze of "Skiffle" and this eventually led him to explore the work of artists such as Lead Belly, Josh White and Big Bill Broonzy.

In the 1960s the new craze in popular music was Rhythm and Blues, also the impact of Davey Graham was being felt. In 1961 Renbourn toured the South West with Mac MacLeod and repeated the tour in 1963.On returning from the South West Renbourn and MacLeod recorded a demo tape together. Renbourn briefly played in an R&B band while studying at the Kingston College of Art in London. Although the British "Folk Revival" was underway, most folk clubs were biased towards traditional, unaccompanied folk songs, and guitar players were not always welcome. However, the Roundhouse in London had a more tolerant attitude and here, John Renbourn joined blues and gospel singer Dorris Henderson, playing backing guitar and recording two albums with her.
