Here is an excerpt from the story in the Tennessean...
Adcock, a well-known, well-traveled banjo player, recently underwent deep brain stimulation surgery, a cutting-edge procedure used to cure tremors. The surgery not only did that for Adcock, but also restored his dream of continuing to play music professionally.
The uncommon part was what the doctors asked him to do: play music while they worked on his brain.
A videotape of the Aug. 25 procedure shows Adcock lying on an operating table, picking an original song on his banjo while, on the other side of a plastic curtain, surgeons and nurses do their work.
