Jazz Musicians and history?

Patton fell under the spell of guitarist Henry Sloan and would follow him to gigs.By 1910, he had become proficient as a performer and songwriter, having already composed "Down The Dirt Road Blues," a slow drag called "Banty Rooster Blues," and his theme song "Pony Blues."Son played various National single cones ( Duolians and Style "O"s), playing slide with a piece of copper tube(?) on his third finger in "Spanish"(Open G - DGDGBD) tuning. By using his third finger ,Son was able to damp behind the slide and use his pinky for fretting. The copper tube adds a gritty sound, which works great with a Duolian, Steel bodied "O" (or a new Delphi). Son's lyrics reflect the stark life he lead. This is the Delta Blues.
