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.

Leroy Carr was born March 27, 1905 in Nashville, Tennessee. His parents were John Carr, a laborer at Vanderbilt University, and Katie Lytle, a domestic worker. After his parents separated, Carr moved to Indianapolis, Indiana with his mother. Carr was a self-taught piano player. After dropping out of high school, Carr travelled with a circus, and in the early 1920s served in the U.S. Army. Carr returned to Indianapolis and worked in a meat-packing plant. He was married and had one daughter. Carr was convicted of bootlegging and served a year at the Indiana State Penitentiary.
