This is one of my favorite shows and thought I would post a nice review from Deadheads Taping Compendium Vol #1 to help celebrate this magic daze. Listen to the show and feel the dose kick in at China Cat. I swear I have never heard on tape a more historical moment then that where you can actually feel it kick in on tape.
