Leroy Carr & Scrapper Blackwell

Leroy Carr (March 27, 1904 or 1905 – April 29, 1935) was an American blues singer, songwriter and pianist who developed a laid-back, crooning technique and whose popularity and style influenced such artists as Nat King Cole and Ray Charles. Music historian Elijah Wald has called him "the most influential male blues singer and songwriter of the first half of the 20th century". He first became famous for "How Long, How Long Blues", his debut recording released by Vocalion Records in 1928.
