"Blind" Willie Johnson (January 22, 1897 – September 18, 1945) was an American singer and guitarist whose music straddled the border between blues and spirituals. While the lyrics of all of his songs were religious, his music drew from both sacred and blues traditions. Among musicians, he is considered one of the greatest slide or bottleneck guitarists, as well as one of the most revered figures of depression-era gospel music. His music is distinguished by his powerful bass thumb-picking and gravelly false-bass voice, with occasional use of a tenor voice.

Huddie William Ledbetter (January 1888 – December 6, 1949) was an iconic American folk and blues musician, notable for his strong vocals, his virtuosity on the 12-string guitar, and the songbook of folk standards he introduced.

Robert Leroy Johnson (May 8, 1911 – August 16, 1938) was an American blues musician, among the most famous of Delta blues musicians. His landmark recordings from 1936–1937 display a remarkable combination of singing, guitar skills, and songwriting talent that have influenced generations of musicians. Johnson's shadowy, poorly documented life and death at age 27 have given rise to much legend, including a Faust myth.

Johnson's songs, vocal phrasing and guitar style have influenced a broad range of musicians; Eric Clapton has called Johnson "the most important blues singer that ever lived".[1][2] Johnson was among the first musicians to be inducted in the Rock and Roll Hall of Fame's "early influence" category in 1986.[3] He was ranked fifth in Rolling Stone's list of 100 Greatest Guitarists of All Time.[4]
