Claiming to have recorded the first blues might not be as big a boast as saying one invented the wheel, but it could be considered in the same department. Once the claim by Chicago jazz musician Floyd Campbell is actually explained in more detail -- he claims to have recorded the first blues by a male singer, not the first blues of all time -- it could perhaps be even considered credible. The recording in question was a session for Okeh in 1929, at which he recorded several tracks including "Marcus St. Blues" and "The Cold Hand Blues." Campbell, who taped several long interviews for the Chicago Jazz Institute, says that classic female blues singers of the era such as Clara Smith and Bessie Smith, also confirmed that he had been the first man to record a blues song.
