Absolutely go. Doc maybe a bit grayer and slower than the first time I saw him in the 60s but he is definitely worth seeing. Besides being someone who really pushed the art of guitar flatpicking (by essentially playing fast fiddle melodies on a guitar)he is a great overall musician, covering a broad spectrum of traditional American Applachian music including ballads and story telling, so its not just bluegrass. Plus he can play a mean banjo too.
