Bluegrass musician Eddie Adcock has been afflicted with tremors that affect his banjo playing. Brain surgery is the logical treatment, but you want to be able to check to see if you’re working in the areas causing the tremors without causing other damage that could affect banjo playing. Solution: have him play the banjo while operating to “optimize the system” so to speak.
I’m usually icked out by surgery videos but this is utterly absorbing. On occasion it actually does feel like The Future around here.
