Feb 11, 1970. The Fillmore East. The Dead, The Allman Brothers, and Peter Green and Fleetwood Mac all wind up on the same stage together. I'm sure I wouldn't remember a thing if I had actually been there, but wow, what a show.
You can stream the concert at the link below. There is a bad splice during Dark Star. Im not a huge Dead fan, but Spanish Jam and Dark Star are just stupid good in this recording.
