 Take the basic concept, move it into the "modern wild west" and what you get out of it is straightforward Texas Blues.It's all in there, endless highways, run-down trucker bars, oil, dirt, cowboy boots, stories about life on the move, all down in Texas, all just as sad as the original Blues (Lone Star Boogie, No Wheels Blues).The mixture of the basic Blues concept with more country and western styled instruments (slide guitars, harmonica) gave the Blues a rawer, yet again still instantly recognizable sound, which has played a major role in music ever since (up to Stevie Vaughan and ZZ Top).
