Grateful Dead, May 8, 1977

Today is the anniversary of what many people consider the Grateful Dead's best show: May 8, 1977 at Barton Hall, Cornell University. I wouldn't go so far as to say it was the Dead's best show, but it's certainly in the top 10, and there are a couple of performances (Scarlet Begonias > Fire on the Mountain, Morning Dew) that have a legitimate claim the being the best performances ever of those songs. 

The show was circulating in tape trading circles for many years (decades even) before the Dead organization were able to get their hands on the master soundboard recordings (it's a long story). I had just gotten a copy before my dad died in 1992 and it kept me sane through that horrible period. The show was officially released a few years ago and you can listen to it on Spotify. If you haven't heard it, you are in for a treat.
