Robert Leroy Johnson was an American blues guitarist, singer, and songwriter. His landmark recordings in 1936 and 1937 display a combination of singing, guitar skills, and songwriting talent that has influenced later generations of musicians. He is now recognized as a master of the blues, particularly the Delta blues style.As a traveling performer who played mostly on street corners, in juke joints, and at Saturday night dances, Johnson had little commercial success or public recognition in his lifetime. He participated in only two recording sessions, one in San Antonio in 1936, and one in Dallas in 1937, that produced 29 distinct songs recorded by famed Country Music Hall of Fame producer Don Law. These songs, recorded at low fidelity in improvised studios, were the totality of his recorded output. Most were released as 10-inch, 78 rpm singles from 19371938, with a few released after his death. Other than these recordings, very little was known of him during his life outside of the small musical circuit in the Mississippi Delta where he spent most of his life; much of his story has been reconstructed after his death by researchers.
