About Slim Harpo
Slim Harpo (born either Isiah Moore or James Isaac Moore; February 11, 1924 – January 31, 1970) was an American blues musician, a leading exponent of the swamp blues style, and "one of the most commercially successful blues artists of his day". He played guitar and was a master of the blues harmonica, known in blues circles as a "harp". His most successful and influential recordings included "I'm a King Bee" (1957), "Rainin' in My Heart" (1961), and "Baby Scratch My Back" (1966), which reached number one on Billboard's R&B chart and number 16 on its broader Hot 100 singles chart. He started his recording career in March 1957, working with the A&R man and record producer J. The record was a regional hit, but failed to make the national charts. Harpo played guitar in his live shows, but he usually used other guitarists when recording.
