Robert Leroy Johnson (May 8, 1911 – August 16, 1938) 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.Johnson mastered the guitar, being considered today one of the all-time greats on the instrument. His approach was complex and musically advanced. 
When Keith Richards was first introduced to Johnson's music by his bandmate Brian Jones, he asked, "Who is the other guy playing with him?", not realizing it was Johnson playing one guitar. "I was hearing two guitars, and it took a long time to actually realise he was doing it all by himself", said Richards, who later stated that "Robert Johnson was like an orchestra all by himself". "As for his guitar technique, it's politely reedy but ambitiously eclectic—moving effortlessly from hen-picking and bottleneck slides to a full deck of chucka-chucka rhythm figures.
