Leroy Carr was born in Nashville 1905 and was one of the first blues singers to use an understated vocal delivery. Francis ‘Scrapper’ Blackwell was born in 1903 and practiced the guitar throughout his childhood and as an adult developed a delicate vibrato blended with string snapping. The Indianapolis duo popularised the guitar-piano blues duet. Over their career they made over 100 sides from 1928 – 1935 when Carr died. Their most famous song is “How Long Blues”.
