Best Grateful Dead recording?

The first Garcia - Grisman album. Great acoustic versions of songs and excellent recording quality! I know I am slipping away from the "Grateful dead" question - but this is such an enjoyable album - I had to include it.

American Beauty on vinyl, In the Dark on cd

Old and in the Way, technically not really a "Dead" album, per se, but still...; recorded by Bear at least I think so...

Jerry Garcia,Peter Rowan, Vassar Clements, John Kahn. Recorded by Owsley Stanley. One of best bluegrass records ever made. Live from a small club in 73 0r 74. Jerry's banjo playing was at its best here and he was in great voice. Sweet harmonies!

For those recommending acoustic stuff, Garcia and Grisman, Old and In the Way, etc., I have to say that "The Pizza Tapes" with Garcia, Grisman, and Tony Rice is not only great music, but one of the most alive and realistic sounding recordings I own. Check it out!
