Robert Leroy Johnson (May 8, 1911 – August 16, 1938) was an American blues musician and songwriter. His singing, guitar playing and songwriting on his landmark 1936 and 1937 recordings have influenced later generations of musicians. Although his recording career spanned only seven months, he is recognized as a master of the blues, particularly the Delta blues style, and as one of the most influential musicians of the 20th century. The Rock and Roll Hall of Fame describes him as perhaps "the first ever rock star".
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 had only two recording sessions both produced by Don Law, one in San Antonio in 1936, and one in Dallas in 1937, that produced 29 distinct songs (with 13 surviving alternate takes). These songs, recorded solo in improvised studios, were the sum of his recorded output. Most were released as 10-inch, 78 rpm singles from 1937–1938, with a few released after his death.
