"Mississippi Half-Step Uptown Toodeloo" from Greatful Dead 08/05/1974 concert.
Lists of "best concerts" have necessarily become lists of "best concert recordings." That's because some concert recordings didn't come off perhaps as well as the actual music presented to the audience. The 08/05/1974 concert has produced a really good downloadable concert recording. Thee is a fair amount of time "tuning" instruments early on that I skip. I think the genuine dead heads love those parts too. The transition to "It Must Have Been The Roses" is pretty neat too.
