Wow thats a great list. I watched a doco on the Grateful Dead a couple of weeks ago. It was a great insight into Jerry Garcia and the counter culture at the time. I knew of the Grateful Dead but only started checking them out more a couple of years back.Personally...Sturgil Simpson, Widespread Panic, Bling Melon, Grateful Dead (yes, still..), Railroad Earth, and occasionally some Circles Around The Sun
