Wow, great thread and I won't waste any time restating what's already been said.
I do have an anecdote though. New Years Eve 1991 I was a friend house for a NYE party, and the group partook in some reality enhancement.
I was a total NOOB to the Dead world, just hot for GD stuff in particular. The host put on this weird, psychedelic county music with this blazing sunrise sounding Pedal Steel. I was whacked out of my brain and mezmerized by this music!
All of a sudden I look up and say That sound like Jerry for some reason and the one dude looks at me and says That IS Jerry!. It was NRPS Live NYC 1970 and it blew me away..JERRY blew me away.
Then I got on the bus, and learned everything I possibly could about the band, Jerry, The Dead, etc. (and Alembic too)
So my point is even being a NOOB and out of my mind, Jerry still sounded like Jerry, even on Pedal Steel, and said Hello let me play with your Jello-fied mind for a while
