Life and careerJones was born in Marianna, Arkansas. He started playing guitar seriously after being given a guitar by Howlin' Wolf, and worked as an itinerant musician in the Arkansas and Mississippi area in the 1930s and early 1940s, before settling in Chicago in 1945.
In Chicago, Jones took up the electric guitar, and was one of a number of musicians playing on Maxwell Street and in non-union venues in the late 1940s who played an important role in the development of the post-war Chicago Blues sound. This group included Little Walter and Jimmy Rogers, both of who went on to become mainstays of the Muddy Waters band, and also Snooky Pryor, Floyd's cousin Moody Jones and mandolin player Johnny Young. His first recording session in 1947, with Snooky on harmonica and Moody on guitar, produced the sides "Stockyard Blues" and "Keep What You Got", which formed one of the two records released by the Marvel Label, and was one of the first examples of the new style on record. A second session in 1949 resulted in a release on the similarly short-lived Tempo-Tone label. During the 1950s Jones also had records released on JOB, Chess and Vee-Jay, and in 1966 he recorded for the Testament label's Masters of Modern Blues series.
Jones continued performing in Chicago for the rest of his life, although he had few further recording opportunities. Later in his career the electric bass became his main instrument. He died in Chicago in December 1989.
