Country blues guitarist and vocalist Blind Lemon Jefferson is indisputably one of the main figures in country blues. He was of the highest in many regards, being one of the founders of Texas blues (along with Texas Alexander), one of the most influential country bluesmen of all time, one of the most popular bluesmen of the 1920s, and the first truly commercially successful male blues performer. Up until Jefferson's achievements, the only real successful blues recordings were by women performers, including Bessie Smith and Ida Cox, who usually sang songs written by others and accompanied by a band.
